Greetings AAV.
I have an SC-805 fitted to my V40. I renewed the car battery the other day and then discovered that I had mislaid the code and having guessed wrongly three times the SC-805 has gone into the two hour sleep.
I have no problems with obtaining the code from the local friendly Volvo dealer - the problem lies with the two hour period that needs to pass with the radio receiving 12v from the ignition switch. I have discovered that it needs to be a continuous two hours not two hours cumulative, and as I mostly travel quite short distances I'm going to be waiting forever before it wakes up.
My question is - can I safely remove the sc-805 from the car and supply
12v for the necessary time with it sitting indoors? I have the connector pinout here and it seems to me that all it needs is
+12v to pin 1 and -12v to pin 2 (& possibly +12v to pin 3).
Before I do anything I'd be very grateful if anyone can confirm that this method works, or whether I have overlooked something.
All replies gratefully received
Cheers
