I have a 1998 Audi a4 quatro 2.8. I want to replace the head unit in the car with a CD Player but I really like the RDS feature in the stock deck. Does anyone know an aftermarket deck that

1. Has the RDS Capability, besides Sat Radio
2. Will work well with the Bose premium sound system in the car
3. Will work with the six disc cd changer in the trunk.
4. Will sound awesome..
5. That possibly has a lot of coloring in the display to mesh well with the red interior guage lighting?

I know I need a wiring harness and a adapter plate for the deck as well as a european tool to remove the factory head unit. Is there anything else to worry about?

Also was browsing and I saw some threads on aftermarket decks interfering with the diagnostic scan tools. Any thoughts on this?

Thanks for the help
