Review on 🚗 2021 Eonon Android10 Car Radio 9 Inch IPS Touchscreen Stereo for Mazda 3 2004-2009 – Carplay/Android Auto/Bluetooth/Fast Boot/DVR/OBDII Support | GA9451B by Mike Walters

Head unit installation was easy and works great. I had a little trouble starting the car game, but the new lightning cable solved the problem and everything is fine now. The three cables I had that either didn't work or were intermittent are great for transferring data to my computer. So if you have problems, just buy a new cable. I haven't installed any accessories like a rear view camera yet, but the screen shows "no input" when the car is reversing. This head unit will also work with the factory display and show the station when using the radio, although you will need to set the clock and switch between fuel economy readouts using the steering wheel buttons (which also serve to control the head unit). The sound is good, a little better than the factory radio. The only complaint I have is that the gain is too high so volume 1 is a bit quiet, volume 2 is a good listening volume and 3 is too loud for my toddler, 4-20 is wasted and I would like more detail in my comfortable listening range. I've searched the settings and may have missed it, but I haven't found anywhere to adjust the gain. It was also installed on volume 20 so be careful...
