Hello, can you please show us how you installed the device? i drive a street glide special 2021 and i bought the 4.0 and the gts system doesn't recognize it. Is there a trick? I just can not manage it. with and without jumper. please excuse my language. my english is lousy. Luckily google helps me with that😉
I have the jumper set up, I did have a whim installed but got tired of messing with Harley headsets to make it work. I paid less than a $1 to install the jumper and have had no issues.
