[Only registered and activated users can see links. ]
Any idea what's behind? I thought jcv files were only linked to the corresponding map file...

weird , have you used Express ? Can you compare your file with the one posted in this thread?
Edit: D3084090A.JCV posted in this thread
MD5: D032BAEE32DF464FF065AEDA5F45DD74

hmm - mine has same size: 296.700.567 Bytes
and MD5: D032BAEE32DF464FF065AEDA5F45DD74
...
I will check if the 1390 shows JCV if I remove the unlock files
Tests now done -->
removal of .gma and .unl has no effect (no error message, jv's are shown) on this device
A closer look revealed that D3084090A.gma is 100% identical to gmapprom.gma
and D3084090A.unl consists of 25 characters which are identical to the last 25 characters in gmapprom.unl
