Hey man, I saw you have one of the 2015 VP4 radios in your 2014 truck. Have you been able to update to the new 15.6.1 Firmware? What Firmware version does yours currently have? Mine has 14.16.1 and it will not let me update to the new version. It errors out saying the software update is incompatible with my radio. Just wondering if you have had the same issue.
