I have used Tomtom and a cheap Binatone sat nav. Both worked but i thought basic and slow as i could be at a junction on a motorway before the sat nav. That is confusion on large junctions in Europe. I now use iGO Primo on my android as it has more RAM and better processor than any sat nav i have used. However. My iGO is hooky but if any of you want a cheap sat nav and have an Android phone i have also used Mapfactor.... http://navigatorfree.mapfactor.com/en/ This works very well for a free sat nav. Europe maps are also free and very up to date. It was showing an Aldi store at the end of my street what was in the process of getting built.
