I bought a 770 a while back with Navicore for 150 quid. Gave the 770 to grandad and used the software for myself. Still haven't transferred over the serial number to Wayfinder - but I _should_ have 3 years when I do! [Reminds me, need to call them about that!]

It was _VERY_ useful when I was out and about. Unfortunately European use was VERY limited - I still can't believe they can't navigate from one end of Europe to the other! Their excuse (memory limits) is BS.
