Thread: Kenwood DNX4230DAB missing SD card

Oh, it was definately the internal SD card that was corrupt, in fact I thik it is physically damaged.
After getting it all working with a new Kingston 8GB card, i've just tried to open the GMAPBMAP.IMG and GMAPSUPP.IMG files in the Gmaptool as you suggested and it will not open them at all.

So, i've then tried to format the original internal SD card in windows, it fails to format the larger partition contnually reports crc error.
I then tried to format it in Linux, that too fails, I used gparted to remove the partitions and then tried to create a single partition and reformat that, gparted will not write the new partition table to the card.

I did as you said, route from my home to London, and junction view does work, I was expecting it to show junction images at more junctions (minor road junctions) , I guess, but when on a motorway, or dual carriageway, then they are shown.

No joy with speedcameras, I downloaded the file Boki_Srb suggested, copied the UK cameras into the Garmin\POI folder, but they don't show up on the map, nor when I simulate the route do I see them.
I'll have to play some more today and see if I can progress them.

I am wondering if I remove the detail map from the internal SD card, then put the unit back together, if I can copy the city navigator map and he POI's to a second SD card and keep that in the front SD card slot.
It would make changing the maps easier in future.

I am sure the issues I had originally were all down to the internal SD card being damaged / corrupt, since re-creating the internal card, everything has worked perfctly, the icons and symbols have all come back which were missing on the original card.

Yes, before I embarked on this journey, I updated the nav software to 1.12.0
I tried to put some audio files on the external SD card, the media player doesn't seem to access the SD, only files on the USB stick, I think that the SD card on the front is just for maps.

=====================================================

Hi,

I did post a quick reply earlier this morning, but it doesn't seems to have shown up yet.
I've removed the GMAPSUPP.IMG from the internal SD card, but left the base map on there, also removed the JCV folder.
Now without the external SD card in, all I am seeing is the base map with major roads.
On the external SD card, I have a 'garmin folder', with the GMAPSUPP.IMG for the UK, inside that, a 'voices' folder with a few additional unlocked voices, a 'POI' folder with the UK speedcamera .gpi file Boki_Srb suggested, along with a few other .gpi files for supermarkets and camp grounds etc and a 'vehicle' folder with a few additional cars and finally the JCV folder with the junction view file.

Runing the navigator app on the headunit without the externmal card installed, I am only seeing major roads :-), I then insert the external SD card and it displays loading maps..., then once that is complete, I see the UK detailed maps :-) so it is reading the external front sd card, simulating a route, once on a motorway or dual carriageway, I am seeing the junction view :-)

But, I cannot see any of the poi's, do I have to enable them somewhere within the menu's? I also am unable to select any of the voice files that I copied into the voices folder or any of the vehicles.

In case the earlier reply didn't get through, yes, I did update the firmware in the head unit to 1.12.0 before this journey started, in case that was the reason it didn't work initially.

The original internal SD card is definately damaged, I am unable to reformat it in either Windows or Linux, nor can I repartition it in either OS.


Just following on from the above, I've moved the entire POI and Vehciles folders, from the external SD car onto the internal one along with the contents of the voices folder.
Now, when I restart the unit I am able to go into categories, POI's and select custom, I can see the supermarkets etc that I couldn't with the files on the external SD card.
Same with the vehicles and voices, I am now able to select them, but couldn't when they were on the external card.
Not sure about speed cameras yet I am not able to view them on the map, there are several close to me here, they are showing in the .gpi file when I have conerted it to a .csv I am able to see them, but cannot on the Kenwood map shown on the head unit.

Are they normally visible on the screen of the unit when viewing the map?
