Hi, my Rider 400 switched off towards the end of a ride recently, with a flat battery. It will now not charge either on the bike mount or on the in-car accessory mount, but will charge with a USB cable plugged into the port. Both mounts have 5v at clean, well-sprung pins, and the TT has clean connectors. So, unless both mounts have developed the same subtle problem at exactly the same time, this is a fault with the Rider 400 itself.
Any ideas as to whether this is something with any hope of being resolved. It is not new, so out of warranty, but it is not That old either so disappointing
