Hi. I'm new here.
I'm trying to use my Phatbox from my BMW(sold) into my 2003 Audi RS6. I got the correct cable from Clairparts.com and installed the correct firmware for Audi (7.02) onto the DMS.
Absolutely nothing happens though, no lights etc. I've tried the procedures over and over.
I'm sure I read on the Phatbox forums that this could be done or do I need a special Phatbox to work with an Audi. The other thing it could be is that the harness installed between the HU & CD changer is not correct. (was installed by Audi)
Any help would be appreciated.
BTW, well done for starting up this site.
