Long time lurker, first time poster.
I have successfully hacked Garmin, Routers, Wii's, etc... And would like to know if it's possible to update maps in my 2017 Toyota Sienna XLE Navigation using a hack. I see information regarding "Generations", but I can't tell what generation mine would be. I've also searched hi and low and done a ton of reading but can't find any tutorials or any information if hack updating is even possible. If someone could point me in the right direction it would be greatly appreciated. Thanks in advance for any and all help!
