One that looks good, is not to big, and goes well with the interior styling of the A4.

Wouldn't be too bad if Audi supplied their spec for their radio to trip computer interface. Could probably put some info in the area where the radio normally resides.

I have a 98.5 and so the GPS3 fits well into the "hole" where the cup holders used to be. The power supply cord can be easily attached, too. And the antenna goes well thru the back door.<p>Obviously this is not my everyday setup, only when I travel (also to chart the track route for my web travelogues). But then, on my everyday trip to work I don't really need a compass, eh? :-)<p>- Stan
