TomTom Go 400

In hindsight I really regret buying this make/model of sat nav, my first one was bought in Feb, but this month during a rather wet ride, it let in water, Halfords changed it no problem but my real issue is it's inability to allow route planning on a Mac, all I want to do is plot my own routes and transfer them but can't find a way to do it. I've tried a couple of Windows emulators with no luck and now wish I'd stuck to Garmin. Think carefully before switching from Garmin to Tomtom if you only have a Mac.

small fee quite easy to use

Thanks, 'my route app' seems to be the one, I've gone for the 30 day trial before purchase.
