Just bought this truck on 01/25/12. No its not my first Ram. My question is what to do about the navigation, I can't see anything on the screen. It works as far as what you hear but no nothing on the screen but lines?

It is a 2008 Dodge Ram SLT Hemi (with all the goodies)
The dealer is looking for one but you know how that can go

Any Info?? Let me know

Thanks
Larry
