Well this is my first time working with Bluetooth, so it's kind of been an 'interesting' experience to say the least.  I'm going to first plug Centrafuse (CF) again because honestly it's the best front end (GUI) I've used for the carPC environment.  Recently the CF guys have released RC3.1 and with it came a bunch of fixes and additions.

Finally!  With this new kick ass front end, Centrafuse and its built in navigation system, I finally bought a GPS receiver (pictured above).  Well it's not exactly a built in navigation system, more like intergrated.  Centrafuse intergrades Destinator maps.  So it's just a matter of getting the correct maps and a GPS receiver.

Yea!  Another frontend for me to figure out.  Seriously though this frontend looks to be the frontend to end all other frontends.  It's called Centrafuse and it absolutely rocks!  This is probably my third or fourth frontend that I've gone through since I build my carPC.  The problem is that most of the frontends are created by dudes in their home for free.  So the quality isn't always there.  But Centrafuse looks and acts like a completely professional frontend for my carPC control needs.  But then again, Centrafuse is not going to be free.
