I have a 2003 DHS, bought it to temporarily replace my totalled out 2010 DTS Performance. But it seems to be a great car, and I'll keep it even after I find a newer replacement for the DTS.
This one does not have a heated steering wheel, and I didn't realize how much my wife loved that, now all I hear is how she misses it.
I see on ebay that I can buy some (all) of the parts, but I'm not sure what I would need...A new wheel, trim piece for inside of wheel, wiring???
Is it a difficult undertaking?

Any and all advice is appreciated.

Thanks
Greg
