Hi, Michael I believe he used the Globalsat MR-350-P it has been replaced by GlobalSat MR-350PS4 US GlobalSat MR-350PS4 SiRF Star IV Serial GPS
Take care
Absolutely correct Michael.... The review and installation photos on GPS CITY's web site should look familiar to you as well.
OR Where you referring to the Garmin Nuvi 2797 LMT on the dash?
