Ok, so, the MFU is in the Scania, no lights hooked up, just the speaker...
Powered it all up....then the fun begins, pressing the "set" button for 1 sec, it's supposed to flash while I program it to my TX, problem is, it don't flash,it just flashes once then stays on, can't program TX
Also, when I powered it up for the first time, shouldn't it run then shut down when I press the set button?
BTW, My radio is a Futaba 4EX FM 4 Ch.
What have I done??
