My 3590LM has intermittent contact when I put it in the mount.

Thank you for the quick response.

This is most likely the correct solution, but doesn't help me right now.

I am leaving for a trip of about 1500 km today, from Tarragona in Spain to Stuttgart/Germany with Stops in several French towns.

Yesterday I opened the mount and found out that it contains an electronics board.

I cleaned the contacts, using a toothpick and aftershave.

It seems to bring an improvement, at least it charges and the lady talks to me again.

Hope it lasts until I'm home and can buy a new part.

Well, the improvement by cleaning did not last very long.

I endet up, connecting the device to an alternative USB-supply instead of using the mount.

Before I spend money buying a new mount, I'm still trying to find out whether the problem lies in the mount or in the device.

Maybe I'll find somebody, who has the same unit, but still working.
