While in the USA earlier this year I used a Garmin, it used a bean bag mount that I thought was fantastic.
When I went to try and get a Garmin here the guy told me of all the GPS the ones they where having problems with where Garmins, I ended up getting a Tom Tom 910, have had it in Germany and of course here, it has been brilliant. Lots of options, radar traps, hands free, mp3, can be used with iPod and for a small amount per year will connect to the Tom Tom system and auto update speed traps and road alterations and diversions on the fly. The only thing is, I loved the bean bag mount I had in the US but can’t seem to get one for the Tom Tom.
TomTom 910 comes with maps for Europe, USA and Canada, so if you visit there then you are quids in. Spain has fairly good coverage from what I have found so far, if you go to the TomTom site you will find maps of the coverage throughout the world.
TomTom 910 users Tip: If you suddenly find you cannot switch the GPS on then do a soft reset, the small button beside the little bit of green board beside the main mount plug. If you overcharge the battery they can lock up, doing a sift reset clears this. It is not documented i the book and I actually tripped across it on the web on a GPS forum post, saved my day and me from chucking the TomTom out the window 😊
Hope this helps
