Infotainment update

I have a 2017 Mazda 6 and I'm trying to install Apple CarPlay. I need the firmware update, two actually for that matter, and I've seen that you can actually install it yourself, given the proper downloadable firmware. I've realized also that Mazda is taking down any websites that have the downloadable content, making it extremely difficult for me to find on my own. Before anyone tells me to just go to the dealership, they want $300 for the updates, $300 of which I don't have, especially after buying the CarPlay itself. I'm making a trip from NY to SC in a few weeks for a job and really need the Apple Maps to get down there. I understand how intricate this process is, and the warnings that come with it, so if we could skip the lecture I'd appreciate it. So if anyone could provide a SAFE link with the downloads for NA, that would be awesome. I need the 70.00.100A first, then the 74.00.230A
