Thank you for all of your comments. As far as our old Patriot system goes it is about 6 years old and because of the configuration of the dash it is difficult to get it aligned properly to have it work. The factory trained installer has checked it out and he can no longer get it correctly positioned to work. Definitely time for a replacement and another set-up like the Patriot is not going to work. We have an appointment on the 17th to have an Air Force One installed on our hybrid Mariner and on the motorhome. Sounds like it will be easy to hook up once installed.
Again thank you for your comments and suggestions!
