I can only speak to the RER 730N & it does
i have had to use it a couple times, well out into the boonies, where you take paved roads into the woods & then go down what amounts to dirt trails
Some people like to locate their homes well off the beaten path
Sure does but there is a limit it seems. I haven't been able to find out how many miles it tracks for but it's not as far as I'd like to see. Certainly enough if you want to back track to something familiar though.
