code in martech is 2227 but algo says 22276 5 digits (don't know if this is truncated in radio)
I wrote 1234 into your dump and martech says 1234
has code always been 2227
not sure about counter location cheers

This is now quite an aged treath, sorry for that!

i got the same headunit same error. I didn't manage to get into "____" from ERR.
Tried 1H with ignition on and various key combos.

Can someone with exactly this radio tell me how to get it back alive?

Thank you!
