Rider 400 not charging on bike mount despite power
I have 12v at all connections up to mounting plate, and 5v between brass charging pins - but tomtom unit does not charge up. Battery sign stays on with bar showing rather than lightning bolt.
Have tried wobbling it around and changing from landscape to portrait poistion but no improvement.
I see on this forum that a faulty mount is not uncommon - anything I can do to test it?
