Have this part not acquired here, nevertheless would like to comment here gladly. The article offered here can also be found under the name BT-GPS-8 JENTRO the Internet, there is not even cheaper, more on that at this point. Now for the device, the appearance is simple but very functional, because covered with non-slip material so you can simply place it in the tray in the car, there is very safe. Those who want to can still use the supplied magnet. The first charging less than 3 hours, it only via USB mini port. So the computer, USB charger and the enclosed car charger plug. My advice, my PC also provides in the off state to the USB jack 5 V, try great thing easy. Put it mainly in automobile operation while working (ie about 8 hours) in connection with a Nokia 6300 and the free OE Navi Software a. Now to navigate the course depends on me depending on already mentioned Navisoftware. Satellite detection is in my opinion very quickly, so in the street. I first turn on the GPS receiver and before I my software is ready for use on mobile phones, is already the recipient ON. Then everything goes very quickly by equip. The Jentro brakes not miss the opponent, so the phone, announcements come in time and recalculation is very quick. But the highlight of the whole thing for me is I can in the combination of mobile phone and the BT-GPS-8 it JENTRO as motorists, cyclists and pedestrians alike use. Phone (you have actually always there nowadays) in one pocket and the receiver in the other, and even "I find everywhere all I want." I think it's just awesome. Especially as other combinations are possible, such as netbooks. Finally, a word about the costs, it covered only data connection costs, depending on the provider, which are usually in cents range for navigation from A to B by more than 100 km. At the conclusion of the acquisition of the above GPS-mouse is the value of my cell phone has increased many times over, used in combination with very low investment compared to mobile phones with built-in GPS module, and provide very flexible. Therefore from me 5 stars and my full recommendation.
