Thread: Kenwood DNX4230DAB missing SD card

Cheers Butters, all noted, not very experienced with forums etc, i'm too old I reckon!
Anyways, downloaded the NT maps, and the basemap file put them on the card and .... no difference whatsoever.
I can do an address search, which finds the address and street name, when I click routes, or view map, nothing is shown, nor are any icons on the status bar, or the screen.
When I tried to do the update officially using GE from a friends PC and my SD card, it said the system update to be downloaded was was city navigator europe 2013.20, I tried to download it, but got the same 'error installing update'.

after doing all this, in the system setup for the head unit, it is still saying base map missing and detail map missing, so I am stumped.
