What do you mean have it a good old clean?
And what happens if you remove the gsm unit completely , is it that the GSM signal is dropping out and it is looking for an alternative path ? But you don't have one
The gsm device what type of antenna is it , communication doesn't mean it isn't dropping out
Cleaning aside they look like tat around most decor then the place looks like a Chav house cos installer says it looks so cool in shiny silver and matches your hinges lol
Oddly enough I still haven't taken the my mk7 out, if I eventually got a hkc I will have to move it as the white keypad won't look right .....
I think what amps is saying your missing something, unassign and go through it again , as he says if b is not highlighted , one of the steps is missing
Assign all zones and see what happens perhaps
I wonder have you only tried one zone?
What model is it in? I think SCB mode you would but you could stick a wireless as additional on the enforcer rear of property of other is on front
But charging current would do two I think in SCB mode
