I owned 2014 Gmc Acadia slt1. I purchased Oem nav radio from infotainment had programmed for my vehicle never had an issue with am/ fm radio or XM or Navigation. Totaled 2014 bought a 2015 Gmc Acadia slt1. Have issues with Oem navigation radio getting FM stations to come in. Swapped the radio out of 2014 totalled Acadia to 2015 after having it VIN programed with the same Issues. Anyone else having reception issue with only FM stations? XM and NAVIGATION work normal. Is there something I am missing here? Thanks in Advance for any Insight.
