I have an Audi A6 3.2L (2006)... Oh and its the S-Line. It has a Navi (stock) yet it only came with a 6-disk changer. My friends A4's navi (same one) but his car is 2005.5 actually has its navi flip out and he can insert 2 SD cards into it loaded with songs. I find it sad my audi doesnt have that option. Is there anyway I can add an SD card reader and have it all come up on my navi so I can control it off there? Please let me know! hope all this makes sense
