Need help with in-dash nav unit '05 Durango
I'm really hoping someone can help. We purchased an '05 Durango about 2 months ago. One of the items written in the contract was that the dealer would get the navigation system working (there was no disc). Monday I finally received a disc in the mail (#05064033AC) but I continually get an error. At times, it is as if there is no disc installed, other times it says "cannot read DVD-rom". I took it to a Dodge dealership today (NOT where we purchased it). They took it back for their "nav guy" to look at and told me the disc is too old for the '05 and we needed a newer disc. Someone else told me that IF the previous owner used a newer disc, that would have updated the firmware and you could never use anything but that or newer. I guess my question is... is that true? If so, is there something I can do to revert to the original version so it will accept my disc? I'm not sure of what model it is... it is part of a 6-disc changer system in-dash, factory installed (we have the '05 Limited). Thanks for your time and any assistance you can offer!
