Cheers for the reply, after updating the firmware ( which probably has nothing to do with it)everything started to work as it shouldIt could be the cables you tried didn't have all 4/5 wires connected. I have a collection of cables in the house...and only some that worked for my GARMIN Nuvi GPS and many that didn't.
All of them worked to charge, but only 1 or 2 actually worked to transfer DATA to/From the GPS.
As it turns out, the only cables that worked for the MAVIC PRO remote were those SPECIAL cables that only worked well with the GARMIN GPS. Low and behold, after some reading, I learned it was all about those **** extra wires They used to be sold as DATA Cables... and were sold at a premium price beyond ordinary "Charging" USB cables.
When you have the time to go through ALL your cables - try each one and see which work with your remote and which don't. LABEL those that work, as they are the more "expensive" cables... which have ALL the wires connected to aLL the pins in the USB/MicroUSB connectors.
Save all the other cables for Charging Only!
