Hi guys,

I just recently got my first Mazda 3 2015 SP25 this week (second hand) and have been reading up on AIO tweaks and would like to get into it.

On first look the version I am running is 51.00.351 it would be ADR since I live in Australia. Seeing as AIO only supports v55+, I need to upgrade. If I take it to my Mazda dealer they will whack 59.00.504 on it.

Just wanting to ask if it is safe for me to go from 51 to 56? I will be getting my firmware from this thread "Mazda-MZD Connect FIRMWARE Downloads-UPDATED" and using this one "ADR 56.00.513C".

Should it be pretty straight forward or will I run into any issues? This would be my first time doing this and I'd hate to brick my new car's system.

Thank you in advance :)
