Thanks Mike for the info! The GPS route sounds like it may be the way to go. With that unit, is there an antenna that needs to be run to the outside of the car or does it all mount under the dash? I will have to look that up.
My thoughts on the counsel were that I would have to go to a shop to have one built, but just wanted to check 1st to see if there was a source who already make them to fit.
Thanks again,
Charles
