Radio Panel/AC completely out

[tnjromaine]

I have a C70. Out of nowhere, no warning, no nothing, start the car and there is no radio or AC functions. No display in the radio climate panel, nada! Disconnected the positive on the battery, reconnected, started car, still nothing. Checked fuses, they look good.

Would anyone have another idea I can try before taking it back to the dealer? I have only had it a month as I purchased it used.

Thank you for all and any ideas and advice.
