GPS Data Logger??? Storing Lat/Long + timestamp, to synchronise camera data

[Duck]

I’m looking at doing a long bike trip through Africa and want to store my positions with timestamps during the journey, by synchronising my camera and video clocks I will be able to overlay photos and movie clips onto a map afterwards.

I’ve been looking at the zumo 550 but you have no way of backing up GPS sail trail (trip log) without a computer. I want life on two wheels simple and not farting about looking for PCs!

I’ve been pointed in the direction of independent GPS Data Loggers, separate from the navigation GPS. Has anyone ever used one, have info on them or can recommend a model?

Or maybe someone else can enlighten me how to achieve this with a navigation GPS using memory cards?

Thanks in advance for all advice!!.
