Hi, started the update process for my TZtouch2 (V6.3 to V7) about 55 minutes ago and awaiting the "orange" power key light that signals completion of the update (it's still green now) Instructions state this phase should be about 10 minutes, so wondering if something has gone amiss? Have to leave the boat but don't dare turn it off. I'm going to leave it run...if I return tomorrow and still not complete, what is the next step? Thanks.
