hello, first of all i'm sorry for my english!
i installed an 40 gig phatbox into my audi tt bought on ebay with an original vw cable.
so i changed the pins from the vw plug form to the audi plug form directly plugged in on the backside of the orig. audi concert radio. i also plugged the earth pin onto the radio chassis. so far...
after the first switching on the phatbox LEDs goes red and green blinking for about 5 min showing the update of the new firmware 7.2 into the box, following by shutting down the box - both LEDs switched off.
then i switched on the radio and the box started up. the red LED was still lighting but the green one just blinked shortly for each 4-5 secs...
if i wanted to switch to the cd changer/phatbox mode it showed me sometimes "no cd" in the radio display, most of all nothing. there was no way to change in the phatbox mode at all...
i also changed 2 pins (DATA IN & DATA OUT) after reading a post here in the forum, but at one try it also smelled smoked from the pcb!
i quickly unplugged the cable from the box to minimize damages and opened it to have a look on the lower side, but nothing looked burnt. after that the box still worked (but i'm not completely sure).
the dms looks good. it stores music and plays it via the pc. also the dms doctor program shows no failures...
maybe you could give me an advice.
thanks a lot!
