First time owner of Japanese car. Whole life buying american. Glad I made the switch. I love my 2010 Acura TL 3.5 base. But not happy with the Radio. I got used to the NAVI, backup camera and DVD on my 2006 Chrysler 300C hemi. I had too many electrical problems with that car. I'm hoping to get advice or information on upgrading my Base radio in my 2010 TL. Can I get the Tech system installed in my car? Or other Navi system from Acura in my car? Or is there an aftermarket company that makes Navi for base TL's? Please let me know. Thank you so much. Willy....
