2014-2018 Mazda 3 Skyactiv Audio & Electronics
I had my CMU running v56 for a long time now, with some old tweaks, and the speedcam patches. It was working ok.
A few days ago I updated the CMU to v70.000.021A but did not install tweaks yet.
I plugged the Nav SD card again, but it won't load, it stays on "Loading..." forever.
