The latest software update is Version 77. Until now this has included Mazda cars as well. Version 77 does not. If you want Mazda you will have to subscribe separately. There have been big changes to IDS recently to stop pirating by Chinese clones but as usual, those who have been paying for it properly are now being penalised with huge price increases.
Anyone thinking of buying IDS, you need to be doing a LOT of Ford stuff to get anywhere near your costs. Up till these changes IDS was excellent but now I'm not so sure.
