Installed the 1.2 update today. I'm using this in a 2016 Mazda CX-9 for reference. Everything worked flawless prior to updating as long as I was in passthrough mode. After the update everything works flawlessly not using passthrough mode. I'm using the cable that came with the unit I received as well for reference. No reboots, no music playing issues, no problems at all. Adjusted my DPI to 103 and split screen works correctly as well. Hopefully this update helped a lot of those that were having issues. Thanks for a great product! In case it matters I'm use a Samsung S21 Ultra.
