Power for XM receiver in C240

Hi all,

I'm going to install an XM receiver in my 2003 C240. It currently has the basic cassette player head unit (not too good but it'll do for now). If I remove the HU is there a place I can tap for switched 12v? How would I identify which wire to use.

I'm open to suggestions if anyone has better ideas. I've been searching the forums for awhile but I couldn't find a reference to this option.

Thanks for any input....

Search the forum for a thread titled "Finished my XM install" posted by me. That will give you plenty of information to work with.

there is a yellow #12 wire under the gear shift, you cannot miss it.
