OK, an update on the Map DVD. Yesterday as I said I tried to enter the following address "22 High Street, Milton, Cambridge, CB24 6AJ.
I put in the High Street, got some towns listed but Milton wasn't there.
So I changed and entered just the town - not found. I tried the actual name as a POI but that didn't work either. I gave up.
Today, with a bit more time and the manual to hand, I started the entry by trying to set a Memory Point and using the search area, entered the Post Code - then I entered the street and it said "High Street, Milton" :( So it did know but couldn't find it using the normal data entry - complete crock. Lexus could fix this if they wanted to, can't be hard as the data exists so it's just programming (I was one for 40+ years) but now I'm either going to enter my destinations well in advance or buy the Garmin.
Cheers
