Hello everyone, please bear with me as I am new to this site. I have a phatnoise box connected to my concert2 headunit in an Audi a3. It was working fine until I had to take it out of the boot for a period of time. When I came to connect it back again, the headunit couldnt find it. I connect the DMS cartridge to my computer and the software doesnt even find the list of Audi headunits so I can reprogram it. I gave the car to Audi dealer in Bolton only to find out they know nothing about phatnoise?? Please give any advise possible as I am losing the will to live with this thing at the moment and am close to swopping the stereo to an MP3 player. I live close to Manchester/Bolton so if anyone is close by and can help, please let me know. many thanks. Phil
