hi guys at first thx dj_steve with your help my N900 is an android now i the specifications i did read that bluetooth works so my question would it be possible to connect a bluetooth gps adapter to use navigon or tt on it? I dont know if the implemented BT Driver can emulate serial com ports. This is the way usually bluetooth adapter for gps are working. Another little question if i open the musicplayer app i cant see any mp3. But when i use the Photo / backround app i can see all the pictures also from the n900 internal storage. Could anybody please explain what i maybe do wrong? best regards Crown now an Android fan
