My Rider 550 does not charge when connected to the handlebar mount. The connection to the 2 pins on the mount shows 0 Volts. Other accessory (Camera recorder works fine from the same power source. If I connect via the USB, the TomTom charges OK.
I don't believe this has ever worked properly from new. I see other posters with the same problem.
Should I return the cable and mount for a replacement?
