Hi guys & girls,
I'm a relatively new convert to the TT world so pardon my questions in advance. I tried looking around through this forum and other but there doesn't seem to be a single thread that answers most of my questions. So here's what I was wondering about:

Note: my car is an 03 TT Quattro Roadster w/ Concert II Bose pack.

1) aftermarket HU's: what other Audi/VW models can I use for cross-referencing aftermarket HU fit? places like Crutchfield don't seem to recognize TT at all...

2) Are there any significant updates to OEM HU's from 03 to 06? is it easily doable (plug-n-play)?

3) OE NAV: location of some info/pics regarding factory setup, just curious how Audi did it in the TT;

4) Aux in: since Concert HU's have the option to connec to to a NAV and a cell phone doesn't it mean that there is a factory Aux-in?

5) speed-sense weirdness: sometimes my HU seems to change volume and and down while the car is stationary or moving at a steady speed; anybody else observe this?

 

1. yes
2. no
3. not very well, very few tt's have this option
4. yes, but with adapter
5. new hu will take care of this

bottom line_if you want better audio, get rid of bose.

 

Hey man, thanks for the reply. Could you "throw some meat on them' bones"? I would really appreciate if you could add any detail to your reply as answer to #1 as "yes" doesn't really give me much to go on...
Thanks!
