I don't want one for touring and pre-loading routes, I like maps and changing course on a whim.
I do a few short trips each year where a few mates and I pretend to be fit, young things and tackle some mountain routes in the Alps etc. I'd quite like a gadget that will just record the route, altitudes and profiles. Is there such a thing?
Well one option would be to buy a very basic yellow Garmin eTrex with a monochrome display. I'd recommend buying secondhand on
eBay. Bought new, they are (IMO) fairly poor value.
I think a Garmin with mapping is probably the best bet. Even if you don't plan to use it it's nice to have the mapping in reserve. (And I suspect that even if you think you don't want it now, then you may subsequently give in to temptation).
I bought the Garmin City Navigator DVD (buy the DVD direct from Garmin rather than an SD card or DVD from Amazon or whatever). I think it's actually really worth the money even if you plan on mainly using maps. The City Navigator includes the small local roads that would only be shown on the most detailed Michelin (or whoever) maps. I found it extremely useful when I needed to find an alternative to a couple of D roads where bikes were banned, or when I simply wanted to improvise routes across country. The City Navigator also in effect gives you a street map for every town or village you pass through.
The City Navigator mapping also comes with a database of Points of Interest - a lot of this is useless clutter (which you can switch on or off) but it's useful if you ever need to find the nearest hospital with an A&E department, or cash machine.
You don't need to have mapping software to use with the Garmin. I found it useful to put markers on key intersections on the map on the Garmin. I found this useful going through towns or larger villages - although if you are used to using a map on a handlebar bag you might not find this as useful as I did.
Personally I think routing is a bit of a two-edged sword: it's very useful to have something that tells you when to turn, but you absolutely can't rely on the device to plot a route for you - you have to keep a really careful eye on what the gizmo is doing. On the other hand I did find it useful for simple routes like Portsmouth Rail Station to Portsmouth Ferry Terminal.
The free Garmin MapSource (RoadTrip on a Mac). Is useful for route planning. But even if you're not interested in routeplanning you might still find it useful for doing things like marking the location of interesting places to visit or campsites.
Coming to choice of kit. I think you can basically group them into four families:
- the monochrome eTrex GPSes (either with or without a base map). If you can get a secondhand one at a decent price then they could be a very useful intro (or you may find it's all you need). But don't buy new.
- the colour eTrex GPSes. They are (IMO) the best adapted to the needs of touring cyclists: especially if you are interested in being able to store a multi-day route or POIs etc. The battery life is good (a couple of days riding on one pair of rechargeable AAs) and the fact that they use AA batteries is an advantage. The Vista Cx also comes with a barometric altimeter and it will display an altitude profile for the day's riding;
- the Edge family. These are designed primarily for use as a training aid. Which doesn't mean they can't be used by touring cyclists but they have a number of memory limitations which might be a disadvantage. Also the fact that they don't use AA batteries is, to my mind, a disadvantage;
- the touchscreen colour displays (Oregon Colorado etc). These are very nice, but they are more expensive. A larger screen is an advantage if you need to scroll around a map, but it (I assume) comes at a cost of shorter battery life. I have also read criticisms that the display isn't bright enough for really sunny days - I can't vouch for this.
