Can anyone provide me with advice as to whether it's advisable to invest in a GPS in Doha? I haven't looked into this yet because I'm not driving (can't buy a car because I don't have my RP). But I just received a panicked email from my daughter in the US telling me that her car was broken into and her GPS was stolen. She wants to invest in another one to use there and I thought that, if we're going to be buying one anyway, I might as well get one that I can use here. Thoughts? Magellan, Garmin, other brands?
