| Andy,
I've been using a tomtom go for a couple of months now - very easy to use straight out of the box. Also easy to download the UK speed camera database. The only downside so far has been that you can't enter a postcode for the destination. I believe Navman make an all-in-one that is designed for bikes.
I shied away from the pda ones because they always seem to crash at exactly the wrong time. Not a problem for me, but Mrs Chicken is a technophobe and wanted the simplest solution. The pda kits start around £300. If you already have a pda, you can get a gps add-on, car kit and software for a lot less. If you don't have a pda, I have a compaq ipaq that you can have for the postage and a drink - I'm warning you though, it is $h1te (why else am I giving it away!)
Whatever you get, you should find a way to get the voice prompts to your helmet - without these you won't know when to look down.
cheers, Chi |
