I have a question about my standard Audi CD changer, can I get a 10 CD Sony one for example and just plug it in? 6 CDs isn't enough and sometimes my homebrew CD-Rs don't always load (I think it's getting a bit picky in its old age!) My car has the BOSE fitted, so not sure if that means I'm going to run in all sorts of issues....I hope not! Has anyone else upgraded the CD changer and if so, is it straight forward? Thanks.
