I recently picked up a 2011 Wagon from a family member and LOVE it. Sadly, it was a bit basic on the options/features, but the deal was too sweet to pass up. I'm hoping to add a few upgrades to the system in the coming months.
The COMAND came with bluetooth/AM-FM-HD/CD-Changer/AUX-mini jack in the glovebox. I'd like to add Sirius and Nav. The Nav seems pretty straight forward by buying the HDD, adding the antenna and a reprogram. On the Sirius front, I've not found any info on how to do that. My dealer says it's not possible.
Does anyone have a list or diagram of the inputs for the back the COMAND unit? Or any advice/tips on how to add either the Nav or Sirius?
