I was looking at Navigation lately for my 08 t&c lx and i do not know whether a navigation system needs extra accessories to be installed.

I saw a Media system on ebay i wanted to see if it costs too much as $650.00 or should I find something better for better price..?

 

You never know what you're getting on ebay when it comes to pre-owned car audio, especially oem parts. I recently purchased a nav unit for my 08 Chrysler 300 through a site oemautopartsco.com. It's was $999, but worth it. Looks brand new and came with everything necessary.
