JY-UQ124 = RK3188 Quad Core, 16 GB Flash, 1024*600 Screen
JY-UQ127 = RK3188 Quad Core, 16 GB Flash, 800*480 Screen

They all have the same appearance. They have a 7" screen, with a single large knob (push for power), and a couple of buttons on the left side.

Hotaudio Model 2100: 2DIN 7" 1024x600 RK3066 Android 4.4.4

Hi Guys,

I've been searching but couldn't find info on this head unit. It looks like they upgraded the screen to 7" 1024x600 on an older dual core 1.6Ghz RK3066 to make a universal 2DIN unit. It seems to be a recently released model, looks like a nice unit for a good value.




Does anyone have this HU or know about it? Hotaudio seems to be the original manufacturer, is there a better known clone of this unit?

All I can find searching for "Hotaudio 2100" are some posts on a Russian forum:
