The phone side of the carkit works beautifully on my new car head unit. Contacts/call log/phoning etc.

The issue i have now is trying to browse the audio/picture files on my N900 via the in car headunit over bluetooth - i can initiate playing the audio files from the phone but cannot browse the folders on the phone or see the name of the track that is playing on the headunit, my partners iphone can cope with this but my trusty N900 cannot !

The N900 and SD card inside are both formatted to Fat 32 which is compatible with the head unit.

Any help would be greatly appreciated??

TIA
