KeyChain GPS f/Smartphone

Rating : - Keychain GPS
I connected this gps to a blackberry 8703e from verizonwireless. The gps on the phone is not really a gps/ 1700 meters off using google maps or live moble. So I got this keychain gps and downloaded live search on my blackberry. The other gps keychain with microsoft trips is only used for the laptop so i didn't get that one. The mobile phone or blackberry uses the live search, which is free.

All you have to do is download the app and connect the bluetooth. Another thing is that the manual said to use 0000 as the passcode but it didn't work. My passcode was 1234. I also found out that while using a laptop bluetooth it doesn't use a passcode. 0000 won't let you connect.

On the blackberry and once connected to the bluetooth. If you go to live search - options- configure and choose gps20c/ spp s.

Compared to the blackberry gps, it more accurate- on the dot- than the blackberry gps which is sometimes 4 blocks away.

The only bad part is that sometimes it takes awhile to connect to a satellite. Finding the satellite varries. Sometimes it could take 5 min ,or even 15 minutes or more. But once you get a signal you can drive down the street and watch the gps dot follow you.

I was so close to returning this at first because it didn't connect using the passcode and it seemed like it didn't want to find a satelite. But I'm glad I didn't.
