bbf2530 thanks so much.
I tend to hang on to our vehicles. Our 96 Explorer and 230,500 miles and still going strong. So I like personally like to have the warranty.
Does anyone know of a good place to purchase and extended warranty? I am talking about price, I do want to get a factory warranty. I have 25,000 miles on mine so I am not in a dire need. However I would like to purchase one.
Thanks
The 2007 and 2008 systems are interchange able. The 2009 and 2010 are interchangeable, however you cannot go from a 2007 unit to a 2009 unit. The newer units have a hard drive in the unit itself.
