Well i bought my Audi S3 about 3 weeks ago and what a superb car so far! Only trouble being music! im used too mp3 stuff so looking how best too upgrade my ice in the car I have the Concert Headunit with single CD/Radio it has the Bose system with sub in boot. however is it likley that its wired for a cd changer? or only the tape player head units? Is it still possible too fit a cable for a phatbox?? easy? i really do not fancy pulling off all the trim so any help much appricated? I think i prefer the idea of the Phatbox as too the Ipod link because of ease of use. where is best place too buy a phatbox which iam garenteed too work on an 02 S3? USA? VAG? ive read all other posts i can find but kinda got confused by some!! so any help appricated!
