How do I get an update for my SMART2GO GPS Maps?

I have a GPS powered by SMART2GO
(NOT a mobile phone)
with maps and it is working pretty well but the maps are about 8 months old and I keep finding that roads have altered since the map was installed.
I have tried going to smart2go.com but it is totally unhelpfull. It is all geared for phones.
Has anybody else had this problem and how did you solve it?

Have you registered your Smart2Go, that is where you get the updates. See the link below –

Hope this helps.
