Ok it's a nightmare trying to trawl through websites trying to find the right info on all the millions of sat nav units, features, whether they have card readers, what's the card size limit etc etc. What I'm after is a basic unit (not interested in traffic updates, lane assist, reroute, map share and the other gubbins). I want something with a decent display to use as a travel guide when in hotels and in between places on a tour. I can display a map and see that there are loads of restaurants and pubs next to a harbour say so looks good next place to visit (and there's a Tesco for the missus ??) I saw some RAC ones which looked great and can download Lonely Planet Guides. I did read though that there is a limit to POI categories and the units start having display problem if too many. I have looked at my mates TomTom and it's ok but not great. Perhaps I need an iPAQ instead and use MapPoint on it. Or is there some other device that is sort of more biased towards quality maps rather than navi features etc. iPhone perhaps ? I might just spend £80 on the RAC one and see how it goes.
