I recently purchased a 2009 ML350 and cannot get Sirius Radio to stay connected. The initial activation worked about 10 minutes. The reset worked the same, but subsequent resets, even "hard resets" at (2) Mercedes dealership service, have done the same. The second shop said the Command Unit could be replaced, but with everything else working, I hate to incur such an expense. Any suggestions? Thanks!

 

Satellite problem fixed by Sirius, probably permanently. They do it by putting your SDARS unit's EIN into a "PROTECTED TIER" in their computer system so that when they tell their system to send all the channels for free, our radios do not accept more than the total number of channels which our head units were designed to hold which causes them lock up.

The first couple of generations of the SDARS unit(s) can't handle any "MORE" than 140 channels total. It has nothing to do with the channel number(s).

All of this came about when Sirius decided to upgrade their service to what they call the Plus or Enhanced package with more channels not taking in consideration the MB, Mini and Range Rover's specs. That killed it for a lot of us.
