i have an oem nav radio in my 2006 f150 that i got on ebay. everything works except the subwoofer is not enabled. radio is 7L3T-18K931-DB, S/W 3.040000
when i do the 3-6 diagnostics, it shows up that the subwoofer is "not enabled". local ford dealer, 2 of them, can't program it or don't know how...can anyone help? i see i can send them off but i don't want to do that....have a big gaping hole in the middle of the dash.....help please
it would be best if you contact garmin directly. when i have questions about my gps i contact the official web site (newelectronx) and get help fast, so i know you should have no problem with doing that with garmin
