I've managed to get the Peak District and Brecon Beacons maps to work. Previously, I had used Fast Image Unlocker to unlock them. It didnt report any problems so I assumed it had worked OK. I have now tried Garmin Unlocker Alternativev 5.71, which appears to have done the trick and these maps are now visible. Only problem now is that the Lake District map is already unlocked and GUA doesnt like that.
Nearly there!
Are you sure you dont have 2 maps with the same FID ?
Lake district has FID 400 .
I donnow which one are you using ,but Great Britain National Parks 1-50K one has FID 400, while Garmin GB Discoverer 1:50K - Full Coverage has FID 2043.
You have to navigate to get to the good.
Galaxy S5 Kitkat 4.4.2 / Nuvi1200->1250 / Nuvi3790T->34xx / Nuvi 2200 / Nuvi 66 / Oregon 600
I dont think so. Is there an app that will tell me what the FID is?
At one point I formatted my SD card and put only the Lake District map on it and it still wouldnt show, so I assume its not a clash between two maps.
Are those maps better than 1:50k maps, when I zoom In, I can see a vector map at the highest zoom but no raster map.. weird no ?
Anyone tried to go to 50m zoom and saw a raster map ?
Thks
look at post 15

I have had a look at the img files using gmaptool. The Brecon Beacons and Peak District report FID 400. Discoverer 50K All reports a FID of 2043. I dont think a FID clash is the problem (as I mentioned, I had tried just the Lake District map at one point). When I look at the Lake District img, it reports the following:
.Reading file C:/Data/Garmin Discoverer Lake District 25k UNLOCKED/GMAPSUPP.IMG.
Wrong header (DSKIMG GARMIN), file C:/Data/Garmin Discoverer Lake District 25k UNLOCKED/GMAPSUPP.IMG.
File: C:/Data/Garmin Discoverer Lake District 25k UNLOCKED/GMAPSUPP.IMG, length 415948800
File format errors (3)
There were errors, result is faulty.
End
I think I have had two problems.
1) The locked img files were not being unlocked by Fast Image Unlocker. This was resolved by using Garmin Unlocker Alternative.
2) The Lake District img appears to be corrupt. I have tried downloading it again, but I get the same error.
