My radio is in demo mode, it says press Volume Knot button and when I press it nothing happens. I tried to unplug radio and plug it back in into power, I tried to reset radio by holding reset button key for 5,10,30 seconds while in power and without power, plugging it back in, it wouldn't work. I tried to hold 3,6 while turning it back on and then pressing 1,2 , nothing happened still in demo mode asking to press volume knot. I opened front radio panel and cleaned all contact with alcohol brush, still same. I sprayed WD Spray onto volume knot button while its opened still same. I retouched soldering points of volume knot button if it had cold connection to resolder it back on, still it doesn't work, asking me to press volume knot button. Anyone has any idea what can I do? Tried other radio, it works perfectly so its not my installation.
Ha bhai dono wire nikal kar battery ke dono pole ko sand paper se saaf karlo fir dono wire connect karo uske baad ignition on karke music system ko reset karo thik ho jayega
