I have a 2001 A6 2.7T that someone upgraded the original radio with the MMI nav/dvd system. I have three questions which I have researched and am more confused now than before.

1. How or can I get the steering wheel controls to work they do nothing.

2. Can anyone tell me what XM satellite receiver it is I need? Is this based on serial number? The Nav disc is from 2007.

3. At low speed if I ride over a small bump or other irregularity in the pavement I get a sudden shuddering in the front end which once I stop resolves and then the car rides and drives fine. Do not notice at speed on the road over small irregularities? Any ideas?

 

The steering wheel is one of the most important parts of a car. Unfortunately, many cars in the dealer's showroom do not have steering wheels that suit the customers' personal tastes. This article provides some helpful tips on replacing a car's steering wheel.
