Guide for updating the MCU firmware on the SMARTY Trend units.
Detailed instruction for updating the MCU firmware on the SMARTY Trend car navigation units.
Attention!!! Don't update MCU without the need! If you have no troubles with CAN-bus module, Steering wheel buttons, Bluetooth, Wi-Fi ..etc then you don't need to update MCU. Sometimes the unit can be bricked after MCU updating. In that case, the unit should be repaired in authorized service centers.
Before flashing new MCU you should check the current MCU version of your head unit. Go to Settings => Information => Tap 5 times quickly on the "MCU Version". Now you can see applied MCU, please record that information, you will need it in future.
