Maps for Garmin Edge 800
I have an Edge 500 and am thinking about upgrading to the 800. I was going to put it off until holiday-time (when I'll take my bike and doubtless be riding on unfamiliar roads). However I'm re-evaluating that after I want on a familiar ride last week and missed a turn 'cos I was daydreaming!
Anyway I'm a bit confused about the available maps though, was wondering if anyone could help? Not least since the "map" side of things appears to be responsible for a fair part of the total expense of the system.
- the UK Ordnance Survey option - fortunately this option is clear to me, though I would probably class this as a nice-to-have rather than a necessity
- the "City Navigator" maps. These are the most confusing. What type of map should I expect here? Something akin to the one I see on my car satnav? And bottom line, are they any good?
- the Topo maps. Are these just the non-UK equivalents of the Ordnance Survey maps? So if I bought TOPO France, for example, I'd see IGN maps?
Aside from the differences in the maps, presumably all can be used to calculate a route somewhere?
Putting money to one side for a moment, my preference would be to have the OS maps. However when I think about holidays, we regularly go to France, last year we went to Luxembourg and I ended up cycling in Germany too. So my ideal would be not only having the UK OS map, but having the (topo?) maps for a couple of other countries also. Bringing cost into it, everything then becomes very expensive - several hundreds. Contrast this to the City Navigator, with which I can get the whole of Europe for £75.
One other question, not so much the maps but on the memory slot. I know it is micro SD but haven't been able to find what the maximum size of the card can be. For example I can fit a 32GB card into my phone, but many devices will baulk at a card that size. I believe when you buy the Garmin maps on the cards, they come on 4GB cards. This might be enough for one map but if I did end up buying two or three maps... just wondered what kind of card capacities are people using?
Also, be useful just like to hear peoples' general views. Thanks.
