Kenwood DNX7230DAB head unit, 2013.

Map update now available from Garmin, so followed the instructions:

SD card into unit, press "update map"
Xml file transferred to sd card (8gb card)
Insert card into pc, garmin express opens and registers the unit.
Follow map update link, pay £50
System downloads maps onto sd card
Insert card back into kenwood unit.
Doesn't transfer maps. Unit just says "reading device" and stays like that for 3 hours, with engine running ffs.
Phone garmin. Hour later, after checking structure and type of files downloaded, they cannot help. Say contact Kenwood.
Try that. All their help links for this unit lead back to garmin.
Garmin refund my £50
I still have the downloaded files.

Anyone with any ideas please?

No direct experience with that unit but wondering if it needs a firmware update to read the new maps?

Solved. If anyone else has this problem, the new map and associated files are too big for the Kenwood storage, 7.7gb. The map has to be activated on an sd card and the head unit set to read the map from the sd, not from its own memory; so the card has to be left permanently in the unit.

Hello,

Maybe far feched but I have somewhat the same problem, my garmin express tells me there are map updates for my DNX7230DAB but when I want to download it it gives a fault, tryed on 4 different comps, reinstalled Garmin Express, tryed with different sim cards, all firmware updates are done.
@nutsyH did you encounter the same problem at somepoint or is it just me, if you still have the official files from Garmin can you please provide me a copy, I am willingly to pay you a small amount of the 50 pounds it costs.

Thank you,
John
