Just had an email that new maps are available.
Hmm, it doesn’t fit on the original 8GB chip, not enough space and was offered the option of editing bits out or Exit. Exited.
I prepared a 32GB chip with the old data and the Mazda Toolbox accepted it and is right now downloading the update, it may take a while…
Four hours later (slow copper BB) I have a newly programmed chip, with 7181MB of data for map of February 2019.
