Its not for the blindspot, but the trm module might be related. Log onto your vehicle dash or check your ap to see if it applies to hour vehicle. Some have been getting them ota..
I have self-contained cb and the same gmrs. Both hooked up to switch 4. Separate antennas. No probs. Not sure what yours could be.
Make sure everything is grounded properly at antenna and radios.
Check fuse under hood for the aux switch 2 you used.
Stay the hell away from center medians and shoulders. TN is notorious for taking their time cleaning highways. Prob because the brainiacs in this state have ridiculous speed limits and they are chicken to go out there and clean them. Frustrates the hell out of me....
Maybe so, but not this time. I've bought many a vehicle in the last several decades, mostly Fords.
I had a 21' Powerboost F150 that the mothership bricked overnight with bad software.... They ended up replacing the module for 900 bux because they couldn't fix it and I got tired of being a test...
Mine was born in mid Dec 2025. I bought it a couple months later. Never had probs up until recently for no reason as I drive regularly.... happening to my wife's as well. Coincidence? I smell a bug in Ford's mothership.
Whelp froze my arse off and did the update. Damn thing would not let me update the ACM module no matter what I tried.
SO, either Ford has ACM locked out (not first time), or something is corrupt. Couldn't even ping it via FDRS.
But I'm still thinking the TRM module along with Ford pass app...
