I have an 03 Disco and I'm considering XM. I'd like a really nice clean install as well as clear sound. I did own a D1 and was familiar with the factory radio but do the D2s have any type of inputs to connect any aftermarket accessories? Any suggestions would be great. I did a search and read a few posts about XM etc but nothing really about connecting and mounting. I've considered mounting to the over head console (no roofs). Thanks.
