I'm hoping someone else has had this problem, or a similar one and can give some input. About a month ago, the radio in my 2013 C30 started cutting out, then cutting back in every few minutes. After about a week of this, it cut out and never came back on. This affected the radio, CD player and hands-free phone. The display still shows the HVAC information, so it doesn't seem to be a power issue. When you turn on the radio, the time comes up in the upper left corner, but no radio display info and no sound. A Volvo mechanic friend connected his laptop to the OBD port and the program indicated that the amplifier appeared to be fine and no fuses were blown. However, it did NOT indicate what WAS wrong. He opined that he thought it may be the "bluetooth module" which I know nothing about. He said that it is inline with a cable connecting the head unit to the amplifier. He said that one way to confirm this would be to locate the module behind the glovebox, disconnect the male and female plugs from the module, then plug the male & female plugs together. If the system then works, then the module is bad. He also said that, if it IS the bluetooth module, that it's a Volvo-only part and very pricey. Before I blow my next weekend doing this, I thought I try to crowd-source a solution from the SwedeSpeed community!
