Maxidot not communicating with head unit, amundsun

Hi my girlfriend has a 14 plate rapid spaceback.

I've installed an Amundsen plus. It all went well untill the maps froze, I've managed to fix this now with a new antenna.

However while trying to figure out why it wasn't working I disconnected the fuse for an hour to see if it would hard reset to fix the problem, but now there is no communication to the maxidot display.

It's showing the control module is incorrectly coded:

19 Gateway

The code for the head unit is:

Does anyone if there is an issue with this coding?

Thanks
