Thank you all, phantastic , I have hope to get it fixed. I dont want to have technicians on board who start a De-,Amel-isation !
I add the information from Stephane G / Pochon La Rochelle.
I think the best and easiest way is to add an extra GPS NEMA 0183 .
I found online TriNav GPS 160 NEMA 0183 - good choice ?
Perhaps Dean and Arno may send more informations ?
Thank you very much
