i just recently bought a new f90bt with 2.0 firmware had it professionally installed with a seasoned installer with the dvd bypass my bluetooth does not connect with my 3g i phone or old version iphone or a friends samsung phone ive followed the commands and instructions also the dvd doesnot work properly after accelerating 10mph and deceleration below 10 mph the screens warns of parking brake wiring issues and safety issues watching dvd from frnt seat i have audio i have talked to the installer who is researching also id appreciate some help in this matter thanks

Bluetooth should work great with the iphones, have the installer check his wiring if he did a bypass for the dvd. Could be bad unit if you have no BT working at all.
