GPS doesnt accept the Master code!

[Invicta]

Hi,

Recently had to replace my body computer, which meant a proxy allignment. The problem came after. GPS isnt accepting his Master code. Is it because I have this design instaled: AH1 - tema radionav versione 1.1.x con bussola funzionante

I had the non GPS version, then 3 years ago replaced it with the GPS one. No problems until today.

Thanks for the help.

PS: I'm Portuguese, had to write in english.

Installed the original design and the GPS still isn't accepting the master code. Does anyone have an idea of what can be happening?
