Thread: Kenwood DNX4230DAB missing SD card

Well done you got there in the end
YES there is an internal micro card with the BASE MAP lucky for me got another unit for $30 and copied the internal card to a new one installed it to replace the corrupt card like you tried all my tricks of recovery format NO LUCK now have 2 head unit working perfect with 2020 maps
Yet to do this move the Camera POI and or other up a directory CARD\Garmin\camera.poi did hear KENWOOD you have to put here next time you go maps UPDATE it will then copy to the internal micro card
I purchased off ebay an extension micro cable when it arrives will take out head unit again take off the top remove CD player and plug the cable into the slot reassemble after unit back just have to on left side of console near glove box have access to the card with out removing head unit ever again any poi updates or map errors card removal made easy
Here is link on ebay give you an idea due to COVID been 3 months and still not here
...removed dead link...

Hi,everyone
I`m sorry to bother the community again,but I need help with a Kenwood 4230BTdevice.To soem extent the problem is similar to that reported by member FFRLR who started this thread. The original internal 8gb sd card was corrupted (I guess),so I created a new one with 2 partitions:one small FAT and one large exFAT. I copied all available files on these 2 partitions,but the unit is still not working. The firmware is up to date, last version. Garmindevice.xml is missing and I cannot create it following the suggested instructions on Garmin side and/or this forum - nothing gets written on the internal or external sd card and there is no Navigation interface to go to Setings and so on. Also the map image was corrupted(I checked it with gmaptool),so I downloaded a new one and unlocked it properly.The map should be NTU,not NT - according to the label sticked on the original map case offered by Garmin (I searched for the picture,I don`t have one).At the moment,my best guess is that there is something missing or damaged in the other files.I changed the location of GRM_Nav.exe from the root folder into Garmin folder without any difference in the behavior of the unit. Can anyone ,please, check the attached images and try to find out what is wrong/missing ? It would also be good to know if the two partitions should have the exact size of the original ones. The smaller one is visible only with DiskGenius - I put and removed different small files there without any change.
P.S The size of the partitions (especially the small one) is different from the original due to my inability to create the exact one.
Thanks in advance for any help,
Greetings,
K
