well, i was just wonderin how they work. I bought my car in Boston and therefor it has a boston CD, i now live in Oklahoma city and it does not work at all, it says out of range.
I called the dealer and they do not have them for sale, They told to contact navtech and they want $240 for the whole 50 states.
I only need oklahoma for the moment, do you know where they sell them seperatly? or for cheaper.
thanks
