GPS购买和应用问题汇总
1. GPS能直接连PDA么，怎么连？ 答：这个问题比较模糊，大体来说GPS可以通过串口（就是您用来做同步的那个端口）、CF口、SD口、篮牙等方式和您的PDA连接。2. 有必要买篮牙GPS么？ 答：由于篮牙GPS是无线连接，使用方便，连接设备较广，所以使用的人越来越多。当前的篮牙GPS售价也是越来越低，应该算是比较有延展性的选择。3. 是不是PC上面配个篮牙适配器就能用篮牙GPS了？ 答：是的。如果是已经内置篮牙功能的笔记本，那就不需要再购买此类产品。4. 篮牙适配器那种好，应该买哪种？ 答：现在的篮牙适配器整体质量都趋于稳定，如果经济能力够的话，建议购买品牌的产品，也不会贵太多的。5. USB的GMOUSE可以直接连在有USB口的PDA上么？ 答：基本上不可以。PDA上的USB插槽一般提供给键盘、鼠标、优盘等通用类设备，所以没有含GPS的驱动在里面。6. GMOUSE上的PS2口可不可以接在PC机的鼠标、键盘口上用？ 答：不可以，规格不同。7. 一般GPS的波特率是多少？ 答：4800。现在有越来越多的GPS标示可以提供更高的速率，但是对于GPS应用来说没有太大的必要，有的还会造成系统不稳定。8. 为什么我的GPS总是飘来飘去，就算站着不动也在飘？ 答：早先的GPS由于收星能力比较弱，总是会发生断讯，尤其在城市中用做导航的时候，给出行造成很多不便。后来开发的一些民用GPS芯片，将信号不够强的GPS信号也收入，这样就造成了漂移的现象。但是如果在同样的情况下，较早的GPS产品即会完全断讯，直到可以找到信号够强的卫星才开始接受。所以这是一个比较矛盾的选择，但是随着软件和硬件的不断开发升级，相信这种情况会越来越少。9. 能在飞机上面用GPS么？ 答：GPS是可以收到信号的，只要乘务员不禁止就可以使用。10. 到国外能用GPS么？ 答：可以。11. 刚买的GPS有没有必要配延长天线？ 答：建议不用一开始就购买，待您使用一段时间后就会知道是不是有必要购买了。GMOUSE是不需要这类延长天线的，因为GMOUSE本身就可以到处移动，并且可以吸附与车顶，所以一般也没有这样的设计。12. GMOUSE、CF GPS、SD GPS、篮牙GPS，我应该配哪个？ 答：GMOUSE是有线GPS，一般通过USB或专用的适配线连接设备，自身会带有吸铁石，可以直接吸附与车顶。CF GPS是通过CF口或CF转换器连接相应设备。SD GPS是通过SD口连接相应设备。篮牙GPS可以连接各类有篮牙功能的信息设备。一般的设备拥有一种或几种这类的介面，所以选择的余地较大，如果只做车用，还是建议购买GMOUSE，因为这类产品性能稳定，价格便宜，但是一般只能在车上使有。CF GPS是早先篮牙GPS价格过高的时候推出的一种选择，由于有的设备只有CF接口，所以CF就成了唯一的选择，接下来会有些内含SD插槽的CF GPS上市，对于只有CF接口的朋友来说，这是最好的解决办法。SD GPS由于体积小，所以工艺的要求更高，当然价格也贵，比大多篮牙GPS还要贵很多，所以并不是主流的选择，如果价格还是据高不下，相信慢慢会被市场淘汰，但对于只有SD接口的朋友来讲这个也是唯一的选择。篮牙GPS由于优点明显，时下已是GPS的主流选择。13. 昨天我还能定位，但是今天就无法定位了，为什么？ 答：一般是上一次使用的时候没有正常关闭GPS。请重新启动设备后再连接一下，如果还是不行就对GPS进行冷启动处理。在今后的使用中，务必先在软件中停用GPS后，方可关闭或拔出GPS接收器。14. 一个GPS接收器可不可以同时给多个GPS软件提供信号？ 答：一般不可以。但是可以通过一些虚拟端口的软件实现，正常使用下没有太大必要。15. 我的GPS为什么收不到星（定不到位）？ 答：首先需要了解的是GPS受到建筑和金属的阻隔，所以请确保是在室外使用您的GPS。 如果您是在车内无法定位，那就先将GPS置于车顶，对GPS进行冷启动后再试看看，待正常后再放入车内。 请检查您的GPS是否和您的设备建立连接，如果没有请参看问题3。16. GPS怎么做冷启动？ 答：如果是SIRF芯片的设备，可以使用GPS VIEWER软件。如果是SONY芯片的设备，可使用PCTESTER或PDATESTER软件。17 为何我的电脑找不到GPS设备？ 答：请确认您的电脑是否正确安装驱动程序。如果确认安装正常，请到设备管理器中查询端口项，可以找到GPS所在的端口号，然后在GPS软件中设定为此端口即可。

2008 Sienna LE (8-seater) Aftermarket Install Update
I just wanted to provide some feedback on an aftermarket system I just had installed in my 2008 Sienna LE (8-seater).
After some careful Internet research, I opted for a hard disk-based navigation/DVD/music head unit with a 7" LCD. The hard disk-based units keep all the navigation information on a hard disk or solid state flash memory for fast performance and no need to swap DVD's or use your DVD slot for navigation. These units are generally more expensive than DVD based units, but they perform operations much more quickly.
I went with the Kenwood DNX7100 because it had reasonable reviews and great features plus expansion options. I also added the following;
-Kenwood Bluetooth Interface, KCA-BT100
-Boyo Vision Plate Frame Backup Camera, VTL300
-Eonon 14.1" Widescreen Flip Down LCD Monitor, Model 683 (from www.eonon.com)
-Generic Sienna Fit Kit
-Generic Steering Wheel Controls Interface
I had the entire system installed at Tweeter, etc. in Rockville, MD. I did not buy any of the equipment at Tweeter. They did a fabulous job in one day.
The system looks factory installed and the plate frame with integrated backup camera is just perfect. The flip down screen was very inexpensive ($250) and plays DVD's or other video input from the head unit. The steering wheel controls work and can do quite a bit, like change music folders on a USB memory stick.
A real bonus with the DNX7100 is a USB input cable that permits you to plug in any memory stick and play MP3 songs. It has a folder menu on the 7" touch screen. This works great. You hardly need an iPod. For an iPod, you have two options, a $20 accessory permits you to control some of the modern iPods via the touch screen or you can plug the audio input into the Video (a.k.a. AUX) connector. I had a hole cut into the top of the upper glove box and had the cables dropped into it for ease of use and to keep everything hidden.
Everything works very well. You can use the built-in Garmin nav system on the fron screen and watch a DVD on the flip-down LCD. When the nav system speaks, it only mutes the front speakers but keeps playing the DVD in the rear of the van. When an incoming call rings on a Bluetooth associated phone, the entire system is muted. Caller ID is shown on the 7" LCD and you can press a button to bypass answering an incoming call if you wish (otherwise, it answers on the second ring).
All in all, very slick. The Garmin nav system is great. The only downside is the kludgy Kenwood source selector interface. It works, but it's just awful. It seems like a grade school programmer wrote it and then implemented it without ever testing it. It's OK to use but frustrating to think of how good it could have been. Maybe Kenwood will provide an update - apparently this can be performed quickly and simply via the USB interface.
The back up camera is so nice, it should be standard on vans. As soon as you put the van in reverse, the screen changes to the backup camera, instantly.
Bottom line, hold your breath, $1500 for the equipment and $1000 for installation. However, this is a much better system than Toyota offers in any Sienna.

Where did you buy the following: -Generic Sienna Fit Kit -Generic Steering Wheel Controls Interface According to some websites like crutchfiled.com circuitcity.com, double DIN navs will not fit Sienna. I think 2007 and 2008 Sienna's have same opening for stereos.
Replying to: caravan2
Both the fit kit and steering wheel control interface were provided by Tweeter, etc. and were included in the installation amount I listed. My installation appointment was scheduled about 10 days prior and the fit kit was hanging on a hook above the work bench when I arrived for the install. The installer said they work on Siennas quite a lot.
Perhaps Crutchfield means they won't fit without a kit that they do not carry?
You can call them if you need more information. The installer did say that the 2007 and 2008 Sienna fit kits were the same.
The fit kit is made of a dark gray platic that looks good. I can assure you that double DIN head units fit quite well. The OEM Toyota unit is double DIN. Additionally, the Bluetooth electronics module and the GPS antenna were both mounted under the dashboard, too. Only the microphone, which is very small, is visible above the driver's side sun visor.

I'm jealous, that setup sounds AWESOME.
The factory DVD player forces you into the JBL audio package and adds about what you paid to the price. And that's just for the DVD player, no NAV.
FOURTEEN inch screen! You da man!
I thought mine was huge, at 12.1", but you win! That's sweet!

Is it that obvious that I am a man?! Indeed.
Anyway, the cost between the 13.3, 14.1 and 15.4" widescreens was negligable. However, at some point the entire rear view is blocked when the LCD is open. I opted for the 14.1 because it was in the same physical frame as the 13.3, meaning when it was open, the 14.1 blocked no more rear view than the 13.3.
With the 14.1, about 75% of the rear view is blocked. I had to draw the line somewhere. If you don't feel the need to draw lines, Eonon also offers a 17" widescreen flipdown which is only $320 shipped to the U.S. I'm pretty sure this would guarantee 100% rear view blockage!

Convert your car tail lights to LEDs
Depending on what kind of car you have, there may or may not be a complete LED conversion kit available that would replace the entire lens, bulbs, and wiring with a whole new LED-based taillight assembly. This is the way to go if it's available.
If you have an old Mustang, for example, a company called Classic Mustang makes a slick replacement assembly. If your car is more modern, you'll probably have to Google around and hope that a company in the nascent aftermarket sector makes one for your vehicle. Frankly, the odds are long.
Another way to go, however, is to replace the bulbs in your existing taillight assemblies with LED bulbs. These might not have the same kind of light dispersal as a standard bulb, so make sure you can return them if you find they don't fill the taillight with even illumination. If they do work out, you'll get the long life and instant on/off action that LEDs are known for.

If they do work out, you'll get the long life and instant on/off action that LEDs are known for.
Install GPS navigation
If you're the type who travels to new and unfamiliar lands for work or play, adding a GPS-based navigation system to your car makes sense. Many of today's nav systems give you both audio and visual turn-by-turn directions to almost any address, as well as find points of interest, including gas stations, restaurants, and ATMs.
There are three types of nav systems: built-in, portable, and handheld. Built-in systems usually have the largest screens and can often be combined with other systems to play DVD movies or video games when the nav system is not in use. These systems are permanent and usually require a professional to cut or enlarge an opening in your dashboard for installation. Portable and handheld systems can be moved from vehicle to vehicle, but both generally have smaller screens than built-in systems, which can make programming destinations a challenge. Most new GPS designs offer turn-by-turn audible driving directions.
People into outdoors activities will appreciate handheld units, such as the Garmin iQue 3600, because they go right from the dashboard and into a pocket, offering guidance for hikers, bikers, and boaters. However, driving with a handheld is difficult because the unit will either slide all over the dashboard or get propped up in a cup holder. And it's best to have a passenger along to operate it because the small interface is difficult to use while driving. A 12-volt adapter is useful for keeping the batteries from draining during long drives.
Portable units, such as our Editors' Choice TomTom GO, attach to the dashboard via Velcro or other means. They have good form factors for driving, including easily viewable displays and accessible interfaces. For power, portables include plugs for 12-volt outlets or cigarette lighters. Although portables are convenient in that you can move them from one car to another, they don't exactly blend with the car's interior. A portable GPS unit will make an unsightly bump in the clean lines of a well-designed dashboard.
When installing a portable, choose a place that is roughly level with your instrument panel or slightly higher for the easiest viewing. Angle the screen toward the driver so that it doesn't catch the sun's glare. Make sure it is out of the way of the air bag, should it deploy.
Most built-in systems need to be professionally installed. They usually fit in the same slot as a car stereo, and they include radio tuners and CD players, so you won't have to do without music. The navigation screens on built-in units typically pop up or slide out, which makes for an interesting conversation piece when friends get in the car, but such units can cover other dashboard controls or air vents.

Add Bluetooth
Let's face it: using a cell phone while driving is distracting at the very least but, more importantly, it can be downright dangerous. Hands-free, in-car phones are certainly less distracting, but they have the huge disadvantage of not being portable. However, Bluetooth changes all of that by providing the safety and convenience of a hands-free, in-car phone while still keeping the flexibility a cell phone provides. So by now, you're probably wondering how to get Bluetooth in your car.
If your car is a high-end 2004 model or newer, contact your dealer; your vehicle may already be Bluetooth capable. If this is the case, you simply need a Bluetooth cell phone. The only catch is that your cell phone must be able to communicate with the Bluetooth device in your car, and not all models do. (For more on the compatibility issues, read "The many faces of Bluetooth.") Your best bet is to check with the parts department at your local dealership, which should have a list of compatible phones.
If your car is not Bluetooth equipped, don't fret. Numerous cellular phone and aftermarket companies make adapter kits, starting at about $200. Motorola, Nokia, and Sony Ericsson all make auto kits that work with their Bluetooth phones. Parrot, a leading aftermarket company, offers several different systems that can either be plugged into a cigarette lighter or installed by a professional who embeds the system into your vehicle. The plug-and-go systems are handy for people who want to be up and running quickly or for those who switch vehicles often. The best part about most of the aftermarket systems is that they work with almost all Bluetooth-equipped cell phones.
If you're handy and feel comfortable taking apart your dashboard and miscellaneous covers that hide your car's electronics, you can install these systems on your own. Be aware, some of the kit manufacturers void their products' warranty if they're not installed by a professional.
Whether you hire a professional to install the kit or do it yourself, keep a couple of things in mind. To get the best results, mount the microphone no more than 16 inches from your mouth, either adjacent to your rearview mirror, on your headliner, or on the overhead console. Be sure the path between the microphone and your mouth is not blocked by anything, such as the sun visor or rearview mirror, and isn't in line with direct airflow from your air vents.
While it's obvious that none of the components should interfere with the seats, the shifter, or the mirrors, be especially careful that nothing is in the path of the air bag, or serious injury could result. It's not always obvious where air bags deploy, so consult your owner's manual or call your dealer if you are unsure about installing the system yourself.

Connect your MP3 player to your car stereo
If you have a tape deck, the easiest way to go is with a cassette adapter. If you have an aftermarket CD player (that is, one that you had installed after purchasing the car), it may have RCA jacks in the front or the back where you can connect an MP3 player with an RCA-to-1/8-inch stereo plug cable. Certain stereos even have a direct line-in jack, which looks just like a headphone jack, so you can just use a 1/8-inch-to-1/8-inch cord. Unfortunately, most stock systems do not have RCA or line-in jacks, in which case you're stuck with the FM transmitter method. I recommend the iRock Beamit 440FM wireless music adapter.
