What should I look for in a GPS unit?

[Warthog]

I'm in two minds about whether a GPS is worth the expense.

Perhaps you can help me decide. Around the UK and Europe, I've never needed one, but next year I hope to be off the South America, Argentina and possibly the dreaded Ruta 40. So far, I have a very limited knowledge of what they are able to do.

If I get one for this trip, I'm sure I'll end up using it here and across the channel too.

I'd like to know what people think are the specs and functions I should be looking for, particularly for the Argentina/Chile trip, and what models have these functions. Cheers

The biggest issue is understanding the capabilities and limitations of these things, then matching your requirements to find the most suitable model.
It will always be a compromise.
I wrote a short article recently which may be of some help.
See "GPS Buying Guide" at http://www.bluerim.com.au/Ulysses Review.htm
It is not a comprehensive guide, but may at least give you some pointers on what to look for.
