Yup, TomTom Rider 2 here, too.
I like the Garmin stuff, particularly the breadcrumb trails and the PC software, but I couldn't get on with the jerky screen updates and slow route re-calculation.
Only bummer with the TomTom is that there's no audio port on the bike cradle, despite having the pins in the connector for it, so Autocom users (like moi) have to cough up for the Autocom Bluetooth adaptor and connect that way.

Can't argue with £99 though, Tanzy. Bargainous.
