You have to be careful not to change the its mapnumber else none of the 'detailed' imgs will show uo - ie this number should tally with the one contained in the corresponding tdb file.

I agree ; its a great shame ati is down at the moment.

Latest version of TYPWiz may have solved some of your issues, but if not, the author is keen to offer support , see betatesting at pinns co uk email address

If Mapedit shows your pois then they are included in the img. You can also use img2typ at http://pinns.co.uk/osm/img2typ.html to check if the poi is listed in the img, no need to go the  mp route.
If it hasn't been listed then the problem lies with the redering of the img
If it is included, more than likely, then its is still possible for your GPS unit NOT to show certain pois, however strange this may sound.
Unfortunately some Garmin handhelds and nuvis ignore certain types ie (0x Number) EVENTHOUGH they show up in Mapsource or BaseCamp. Try fooling it by using types reserved for places & cities , ie 0xD00 etc . Check cgpsmapper manual for default type list
