One of the leading top 4 GPS receivers with Bluetooth is the CoPilot Live 7 North America. The receiver features a speech engine, 2D and 3D map view, interest points, routing options, map theme change, street maps, real-time traffic info, etc. This seems to be one of the leading GPS receivers sold on the market. Loading the program is simple and the software includes North American maps, and more than 6 million points of interest. However, The program's multibutton controls are challenging, and finding your way around the menus can take a while.

Another of the top 4 GPS receiver with Bluetooth is the 51 channel GlobalTop G33. It is the latest "ultra low power Bluetooth?" The receiver is amazingly affordable. It features 51 tracking channels, and it supported by EGNOS and WAAS. It has a superb urban Canyon performance. It will work with your computer, cell phone and PDA and is compliant with RoHS. Best of all it will work with any navigation program. However, some users find it gets overheated quite a few times.

The third GPS receiver with Bluetooth we reviewed is the GlobalTop HG 100 HUD. This receiver costs about $20 more than the last model, but it has some amazing features that really has to be considered. Its base is on the high-tech MediaTek and it has ambient light sensors with a speed warning function as well.

It also has an indicator that shows you which direction you are heading and is a very handy application to have around. In addition, you can use this receiver with your PDA, computer and smart phone. Various other features are available also, in which you should compare them with Qstarz BT-Q818X, and BT-Q890 the Nano Keychain with Bluetooth GPS receiver.

However we found Garmin Nuvi 360 portable GPS with Bluetooth best of all. It integrates wireless technology with a microphone and speaker that lets you make hands-free mobile phone calls using your compatible Bluetooth-enabled phone. Simply dial numbers with the n'vi's touch screen keypad to place a call, and to answer calls, just tap the screen and speak directly into its built-in microphone. Some of it's other features includes : MP3 player with pre-loaded sample songs and audio books, JPEG picture viewer, travel alarm, and currency converters, 2D or 3D views; pre-loaded with most recent Navteq-driven maps for United States, Puerto Rico, Hawaii, and Canada, Turn-by-turn directions with actual street names; real-time traffic and weather info, Super-bright 2.8 x 2.1-inch sunlight-readable color screen, Display resolution: 320 x 240 pixels

It never hurts to make a comparison of all the leading systems on the market. At least this way you will know exactly what to expect. However, our absolute best recommendation is the Garmin Nuvi 360 portable GPS with Bluetooth.
