DaOsmo

I have a raspberry pi with libreelec connected in the center console. To that I've connected a 500gb drive, using my phone as remote control. I've ordered a signal booster planning adding a sun visor screen for the front passenger.

I myself gave up and took a trip to the dealer that changed the unit for free. Until they got a replacement unit I loaded a supplemented map in the faulty unit so I could navigate (use my car every day in remote areas)

Bramfrank: had a shitload at work! Well my dealer is still debating with the manufactor so I will wait with gmapprom problem. Did try one time but it complained not compatible with current map. Called Garmin and they did not have a clue due to 3part manufactor not even how to remove a supplemented map. Have tried multipel times to install other map then the osm "openstreetmap" but the same anser when trying other supp map then osm, not compatible upgrade.

I can browse file strukturer insisde Garmin but not rename or delete, error message pops up.

Anyone found a way Of actually get the "actions" in Garmin developer menu and file manager to work? My stereo version ctp16 under Navigation -> Settings -> System -> About press and hold lower right corner above the regular Icons.

Ok while not able to buy Garmin maps right know I have compiled a 4g osm gmapsupp.img just to try. If that works I'll go ahead and try to flash it as gmapprom.img. "Mission" just to see if size is ok and if the unit is ok and only get screwed somehow when Starting and stopping the units read n write process.

Someone that knows storage size iside for basemap and supplemented?

When looking around I find only 1 map present my supplemented osm map. Got me thinking that means like some Of you debated that main map is corupt. So if one got hold Of gmaprom.img and tried flash that, might fix bad/corupt data parts. Hey just thinking here.

OK so I did flash a osm map, and now I can navigate with the open source map. Only problem is the "unlock map" message when booting up, and that the map I flashed is not complete with all addresses.

I'll try with a smaller map. Have multipel parts Of Sweden maps I could try. I'll try later and post results.

Hi, Well this happend to mine to. My Fiat Freemont the europe version Of journey. I downloaded osm map (open street maps) renamed the downloaded map image to gmapsupp.img. placed it on a USB stick inside a folder named Garmin. Put my car on ACC mode put the stick in. Uconnect begun validating. After ca 1 min it asked if I would like to update with the supplemented map. A process that was promped could take up to 2 hours. Did not have time to try that but I will. (Pardon my english)
