My 2002 Volvo V40 radio went into the "off" display...did the reboot procedure and got back to the enter code mode. I got the code from our local dealer after supplying the VIN. Tried it three times and went to "off". Took the car to the dealer and they determained the radio had been replace by a previous owner. They searched the data base after looking up the radio serial number and came up with a new code. Tried that number 3 times getting "error" each time till it defaulted to "off". Called the dealer again and they said I need to buy a new radio....something like $1,200. Can you help?

If the radio code is not getting accepted then radio needs to be replaced.But instead of spending $1200, for radio, you can try getting after market radio for your Volvo and that will save a lot.-------
In using after market radio, you need to get the original factory radio connector bypassed,. that will only let the after market radio to work. At best buy they have all types of radios as well as connectors and wiring's.---------Going to bestbuy will help, they have experience, information, good prices, and any connectors that may be needed to bypass factory stereo.---------- This should help.Thanks.Helpmech.
