TY for the reply. 'scuse my iggorence, but what else would I need besides power supply? Communication cabling? What micropod do I need?? Little lost with this one, but a quick study as a retired elex engineer. Sorry, just need a little pointing in the right direction. With only 18,000 miles on it I'm only just getting to the in-depth DIY aspect. In this case age rather than mileage. Oh, and it says for 2004-2006. Do I underdstand you to say this will work for my 2007? Thanks again.
