Its been a long time since any TT maintenance for me and forced by a rebooting 720 GO I thought it time to replace the old 985 maps. I always struggled with the compatibility matrix, nothing wrong with the matrix its just me. So I picked two maps,FR 1030.9519 and FR 1030.9525. The matrix chart shows 9525 and 9519 as working for NV 9.0XX and newer, good. I loaded 9525 and ran a demo of a short journey I know well. I did not see ALG on an interchange I would expect to see lane guidance. I have not loaded the 9519 map yet but took a browse through the files and there is no CSPEECH file in there, the size of that map is somewhat smaller than 9525.
So I do not understand the matrix and am missing something. 9519 has ticks for IQ&ALG, CSPEECH&ASR, TTS and HNR and functional for NV 9.0XX but no CSPEECH file.
I could cut the post short by just asking "which map for my 720 to get all features" but that ain't how forums work. In short can anyone steer me in the right direction regarding interpretation of the compatibility chart?
PS, the rebooting occurred after applying the 9.541 update via TT home (yes I know ) , maybe a corrupted write, who knows, anyway a clean install cured it.
Edited for a check of file sizes: Something must have gone very wrong with unrar on the 9519 map, I have 352Mb total size but a recheck of the link shows a file size of 478MB. I will leave the post for now but I think I may have answered my question!

I will reply to my own stupidity and let the post die. "Someone I know" probably swiped on his laptop touchpad while unraring an archive (the 9519 map) and did not let all files decompress. I see a 56MB CSPEECH file as there should be.
Please close the thread while I skulk off to the stupids step.

At least you realised the mistake and fixed it...lol

If you want to understand the compatibility chart a little more, read the following:

That's what I should have reacquainted myself with before I started the job. Demo on the 720 shows ALG with the correctly unrared 9519 map.
