My Father has a 2006 M35 and is wanting to add xm to it. Does anyone know if it is prewired and where the prewire is? Has anyone installed it on the M35 and how hard is it? Does the antenna go on top of the backseat next to the rear window? I seached to forum and couldn't find anyone that has done this to the M35...

 

It's pre-wired and here is a link to the installation of the tuner. It also shows the placement for the antenna.

I just did this install on my 07 G35 and it went very well.
