Where can I buy NAV. Sys. for my 2007 outlander?

If you are thinking about buying an in dash navigation system for your Outlander, the best place to find them is at Crutchfield. Go to their website at crutchfield.com and search their site. They have a good price and quality is good as well. Customer support is bar none. The only problem is they are a do-it-yourself system. Otherwise, Bestbuy or Circuit City are selling those too but very limited unless you go for a portable one. I would suggest going for a portable unit so that you can tote it around. You can use it when you rent a car or borrow your mom's car. A good place to get a portable unit is thru Amazon.com. Check out buydig.com and buy.com. Hope you find what you're looking for.
