Mine was one of the systems 'fixed', I didn't expect it to work out of the box, but everything I'd ready said it was an easy fix.
Well in my eyes it was anything but.
Thankfully Mark is a bit of s whizz on things like this.
I use the sportdog training and GPS unit now as I was sick of the Garmin version not having maps. I also had a breakdown with the Garmin that ended up with a expensive fix.
The sportdog has been great, a perfect training aid.
