I am interested in adding XM to my 03 Max but don't not sure which XM unit will install the cleanest and if my BOSE head unit has aux inputs in the rear. I am leaning towards the XM Commander but would like to hear about other experiences installing add on XM units. I would like the use aux input over the cassette adaptor for the cleaner look and better sound quality.

 

I went with the Delphi XM reciever. I tried sending the signal thru the antenna leads and the cassette adapter. I found the cassette adapter sounds better and can actually boost the volume of the stock Bose unit. The Bose doesn't have any aux inputs.
