Updating the firmware from V.51 to V.55 on your own?

Is there any chance to update my 2014 firmware to one that I can tweek with https://mazdatweaks.com and add Android Auto support? I am not near my car right now, but the firmware looks like this:

I never saw an answer in this thread to the question of if either updating the software or "hacking" the software voids the warranty. I imagine it does but want to check for sure. My girlfriend has a CX5 and I just got a Mazda3 and some experience with Linux so I am interested in doing this if it doesn't cause warranty issues.
 
Guys this threadsnfrom 2015 and no you can't use mazda tweaks on the NB1 head unint
