Hello all...

I recently picked up a Delphi SkyFi2 XM radio receiver and car mount
at a garage sale. Everything except the power adapter was included.
The rating on the car dock states that six volts DC is required, but
no polarity is given. I have a number of well regulated six volt DC
power adapters, so that is not a problem.

I'd imagine it to be center positive, but I'd like to confirm that
without smoking anything, since I've wanted to listen to satellite
radio for some time. (The price of a new receiver is ridiculous,
especially if you want one for your home stereo equipment.)
