I'm happy with my Touch & Go. I've never had any problems with glare on the screen. I haven't done any updates to it, might get round to that some time, though probably not. I had just the Toyota Touch when I got the car, but I got the Touch and Go installed later, for work. Its been very useful since that, for moving house to a totally new area. I wouldn't be without it. I prefer having it built in than having wires trailing round and I don't like things stuck to the windscreen.
