I`ve just updated mine. I was offered an updated Mazda Toolbox and the latest
map update was July 2017. It took about an hour and a half, so not too bad.
Thanks for the info…
Also just updated mine, had to download a new tool box to get it to connect to the system,but then the update (July 2017) took just under an hour. Probably because I did it mid morning before all the local kids got their Xboxes out and there was plenty of bandwidth. (I use Plusnet, we are about 300 yards from the ‘cabinet’ and do get at times their claimed 50 mbps)
