Mazda CX-5 CMU - MZD2 region change NA - > EU

[M^Coder]

Yes it's possible and works

It's been a while when I'm testing my solution for regional change, looks like whole procedure passes my quality gates and it's fully repeatable solution (always works).

For most of the time I have adapted NA units with EU software swap.

No DTC's from CMU ! Navigation works (after proper SD insert). All car functionalities available.

I've put a lot of effort and resources for low level reverse engineering.

I'm ready for selling solution or share knowledge for price that compensates my effort.

Very interesting, but what does this gain you? (I.e. what are the advantages?)

For me as a member of EU, we import cars from NA, then we make a regional conversion. NA CMU have only 3 languages, EU units have many of them. Plus I can make a full custom setup for any kind of retrofit. Personally i added PDC + touch DISPLAY panel.

I have made many conversion within my country but I think maybe someone outside my country also might use this solution.

does it require desoldering or removing the speedometer from the car?
i.e reading the chip from the board.

i think it will have to be CMU opened with NOR programmer clip connected, i have done that once. If someone after probably many tries and errors created a map for CMU that a huge step

yes. you need to remove CMU and have direct access to emmc. This is the easiest part
