Hello Fred
You helped me a couple of years ago selecting a map but since then I have been unable to choose one that will work so gave up till now, sadly I face the same problem. I thought I understood and after you explained it seems very simple but I still can't select a map that will work (I attached my info file at the end).
I'm running v9510 Switch on my old TomTom1.
I first checked on the map comparability page and cross referenced the maps on there for v9510 (I wanted advanced features but really only need ALG on my old TTOne) against the metacode page list and discovered that meta is listed for two maps 1025_9386 and 1025_9432. The 9386 map has ALG so I went for that one. Both are ticked green in the compatibility colour chart against my navcore version and they both appear in the meta list.
I get " United_Kingdom_and_Republic_of_Ireland-101852.meta => .dct ERROR " when I try to patch the 9386 map.
After some time I found a thread "Re: Attention! Maps 1025 'fornokey' Error!" and tried that but still the same, although it said in the text that the maps usually work anyway, thought it was worth a try before I pester you again.
Sorry Fred, I have tried many times over last two years and didn't like to ask again, it seems so simple yet I can't seem to make it work what am I doing wrong please?
Best wishes, Dave.
