Sirius and 03 745?
Hi, new here. Just bought a 03' 745. I love it. I have read some posts here. I'm wondering if it is possible to have sirius added to the stereo? Seems to me that it would just be a software upgrade. Speaking of upgrades. How do I get the map upgrades for the Navigation System. I'm assuming that I will be able to update that as more constuction continues.
