thank you for the diagram. As I see the GP 150 has no longer a connection, the new GPS is wired to the junction box and gives data to all instruments etc.
I hope I can manage to do this. I ordered the Tri Nav GPS, because I would like the system is working on 3 satellite systems and should give a good accuracy of the position of the boat and the important thing is I hopefully will have it in 3 days - not in june from china.
Thank you for the help - perhaps I will need more, when doing/starting the repair.
