What do you mean by reset itself? Do you mean lose all settings and return to default? 
I've put one of these in recently https://www.aliexpress.com/item/1005006456272513.html  The unit has been fantastic, it does however reboot every now and then when starting the car but after the bootup it's all there still working as normal.
