I really just followed tracks, on OFM-UK, without beeps.
I've just come back from a tour in France using an E30 in that way**, and really, it wasn't very good. Though my main problem - the coloured Track being hard to see on the too-rendered map - is probably one you already get if you use OFM?
By too-rendered, I mean that roads are depicted as two parallel lines rather than as a single 'wireframe' line. Garmin maps on the old Etrex depict as a wireframe, and coloured Tracks stand out really well on this. The same Garmin maps on the new Etrex show roads as 2 parallel lines, and the Track just kinda disappears in the mush.
The solution is to 'navigate' the Track (loading it like you would a Route on an old Etrex) in which case it turns into the familiar thick magenta line and that works fine.
But also, 'Show on map' by default is off for each track you upload to your GPS. You have to visit the Track menu for each Track you have, to switch it on, which for a 2-week tour with some planned alternative routes on some days, is a bore. And on mine, if you upload another Track to add to the 20 or so already in memory, it has the effect of turning 'Show on map' off again for all the others
Still, at least you can have more than 20 Tracks
And it doesn't rattle
The loss of routing options isn't really a problem - I only ever use 'car' anyway, and unsurprisingly that's still there. As is bicycle if you're masochistic enough. The (useful in big towns) 'Delivery' option has gone though.
** just to try it really. Normally I would use a Vista and on a planned tour, direct turn-by-turn routes, or on an unplanned tour I would use 'Go To' and 'follow road' in short hops of 20km or so, so 4 or 5 of these per day. But Vistas are history, we have to convert to newer stuff sooner or later. (why do developers do this?)
Well - there were some things in Windows 3.1 that I muchly preferred to what I have now on Win7.
