I replaced my china APIM as I had black screen issues, I just replaced my APIM with a LC3T-14G370-BCH and my ACM with KL3T-18D832-FJ everything works great except my station buttons 1 thru 6 don’t work I can tune a station and save it to a button but when I push the button the station does not change, any idea’s?
Thanks
As Built’s
This is what my replaced ACM HC3T-19C107-CK
was programed, should I program it the same?
The only difference is old ACM had CD player new one doesn’t
H series ACM is old. The calibration is different than the new one so the AB will not match up. K and L series are 2020+ ACM’s and the AB bytes will more than likely not match. You have all zero’s in the AB for the first 01 lines and that is wrong.
Well went thru the programing according to the radio as built, everything works fine, still buttons will store the station but will not change to it, the > forward and < backward button advance stations both on the FCIM but on the steering wheel they’re very slow, and no sound from center speaker.
Solved, changed APIM and ACM to the following all buttons work, no delays and 3 sets of 6 preset saved buttons.
Thanks Bill
Center speaker doesn’t work, but on the speaker test the left, right, and tweeters do but no center.
