I am so confused.
Zumo arrived today so I've been playing with it and had it all working fine - music and everything! Except...
Connecting the power cable to a BMW socket and plugging it in by my left knee is fine. Red wire (positive) to centre pin of plug, which I'm sure is the positive one.
However, I also have a little socket permanently attached directly to the battery terminals which I use for a battery charger. I had intended to use this for the sat nav. This works fine with the battery charger, by the way, and it would tell me if I had the polarity wrong. But when I connect the zumo power cable to that socket (using the correct plug, obviously) connecting the red wire to the positive battery terminal, nothing. When I reverse the polarity - which I did just out of curiosity - it seems to work ok. This means the in-line fuse is on the negative outut from the battery.
Am I missing something riculously obvious?
