Just built up my DIYPNP, it connects fine & have put a base map on it from my laptop. BUT when I plug it into the cars loom I cannot connect to it. I am using tunerstudio, comms settings okay on mains power, but not on the cars 12v, when I crank the engine I get comms for a second or two before the screen greys again & not connected message appears.
I have checked the 12v from the loom and that is okay (12v, 10.5v when cranking) I have checked the same on the main board of the MS board and get the same voltages. Also getting good earths on the mainboard and the loom plug.
Basically can connect on mains, but not on the cars 12v, despite always getting 12v at the mainboard
Any ideas folks?
