I bought this antenna https://www.navilock.com/produkte/508_Antenna/60543/merkmale.html
But before the GPS started working again, I was forced to reset the ECU. I disconnected it and took it apart, disconnected the ECU-battery a few minutes. Then I reconnected it and the ECU, waited a while and them the GPS started working again.
I too have problem with the GPS and was thinking of replace the antenna. I did a search and one question come up. Is the antenna active or passive in the scooter? Which one did you bought.

Did you ever find the problem? I have just bought a NGT and that do the same. If I connect the charger direct to one of the batteries it do the same as yours. If I charge through the bike or via the split box it works.
And then I have another problem on top of that, it takes forever to charge the batteries. From 30% to full it can take 20 hours. Half that time if I disconnect one battery and charge one, so it seems that the charger cannot deliver full power…
