Hi Guys!
I am sharing your experiences for a couple of months!. I have used many years PDAs/PNAs to navigate on my travels having quite experience as PDA navigation programs user. But after years you want more and not need to install/remove your PDA each time you get the car and AVIC F-900BT seems to me the solution.
With my background as long time PDA user I have perform a full review of F-900BT on a PDAs/Gadget spanish web http://www.pcdemano.com.
The review is in spanish but you can use google as translator with not very bad result. Therefore I leave here link to this analysis for the possible interest of others forum's people. Possibly I have done some mistake due to lack of some tricks knowledge. If it is so, please commet/correct me.
Regards
