I just installed my RNS-E into my 07 A4 with the Bose/Sirius Package. Few questions if anyone knows.

1) How do you save the route's or certain areas to the directory so you do not have to have the Navigation DVD in?

2) What is the largest size SD cards you can insert into the RNS-E?

3) Is there is a specific protocol to setting up the SD cards?

4) What does the "CAR" button on the unit do?

Thanks --Ryan
