Hi mate,
Did you end up getting to the bottom of this? You mentioned the GSA tabs being used with the factory MB switch screen? Did you add the GSA tabs to the boat yourself and connect to the switch system? Also, what was the code you found to enter the dealer mode in the controller?
Sorry for all the questions! Just trying to see what my options are to add surf tabs
cheers
