I have Rx 300 2000. It was in the garage for a month. After amonth when i tried to start it didn ot start at the first try but started thereafter. Before leaving the car for a month Volume button was working fine. Ever since I started the car after a month there is no volume. When i try to increase / decrease the volume i do not see the volume graphics. I can see the CD / Tape / Radio being turned on and the systems working but no Volume.
Would anyone have any idea about the problem and how it could be rectified?
