I had a Garmin 57. Viofo feels to me like a big step forward. The audio seems a bit weaker than Garmin's audio but I can live with that. Bought the camera for the image, not for the sound. Today I managed to run the wire for the rear camera so now all three channels are up and running!
Installed the front and the telephoto camera using a Dongar adapter from the rearview mirror. I still have to run the wire for the rear camera but I am too lazy. 😆 Telephoto works great if you ever need licence plate number in case of an accident or something.
Normal view vs telephoto view
My first Mazda CX-5 was 2012. The DRL and High Beams share the same bulb. LED bulb can be installed, I've done it with Morimoto LED bulbs. But! A big but! The DRL/High Beams is a reflector, not a projector, like Low Beams. Unfortunately LED bulbs don't work well with reflector headlamp. You will...
So, in conclusion, my conclusion: Mazda software runs just fine. Check your Windows Security settings or your antivirus software settings, most likely it blocks the access to the SD card.
