last firmware for RT4 is 8.20
here is procedure of update:

1. download firmware from: http://kowalma.com/Software CD 8.20.iso

2. burn ISO image on CD at lowest speed

3. start engine, insert CD and wait for upgrade to be done

DONT TURN ENGINE OFF while upgrading!

u can check ur curently firmware on your unit by press and holding MENU button.

this firmware is only for RT4 and RT5 devices, NOT FOR RT3
