The 800 and 1000 are different though, the OP was specifically asking about the 500 which annoyingly when you plug in a normal cable shuts itself down and resets the data.
Useful + interesting, Ta. Slight hijack sorry but on a similar topic – I usually charge my 800 from a dynamo (ie has a variable power output from a B+M USB-Werk converter that has a small inline battery to prevent the ‘charge lost’ screen). I use a charge cable rather than a data cable, as far as I’m aware. When I’m moving at >12-15mph and plug the charge cable into the 800 it picks up the charge and carries on recording or navigating as before. No issues.
But when I plug it in at a standstill then move off, it shuts down, re-starts and has straight-lined my tracking from the start point to the current point, has recorded total odo, time, etc though. Seems to do this when I start riding with the cable’s plugged in after I’ve been stopped for long enough to drain the in-line cell also, electronically it’s the same situation.
I’ll have a read of that link Whitestone, but does anyone know why there is this difference in how it responds to being plugged into the charge cable?
