RADIO Not Working Blank

[mcd0minguez]

I unplugged my factory radio in my 2004 XC90 in order to install an iSimple (iPod/iPhone) integration.

I have checked all the fuses

I have left my car on overnight in the ignition 1 setting

I tried cycling on/off on my keyless remote multiple times

Still! The radio screen is blank. I can press the knob twice and it says "volvo premium sound doby II" for 3 seconds and goes blank again! but won't ask for a code and it doesn't say off.

Can anyone help me get my radio back?

try taking out your non volvo addition and try again ... have you left out the fibre optic network plug? the orange sheathed ones ..

definate symptom of the fibre optic signal not being passed around the car. As Clan said, remove the other bit you installed.

Is the other bit you installed a Dension unit? If so, is the power working to it? If there is no power going to it, then it won't pass the signal back around, so the entire system shuts down.

the iSimple unit does not connect to the radio. I tapped in power/ground from cigarette lighter.

I checked all wires and unhooked car battery for 2 hours... still nothing

Just blank screen but button are illuminated. I can get into menu settings but that's all

so is it an FM modulator?

Did you have to remove or unplug any of the orange fibre optic cables? are they all in the correct place?

if you removed the headunit, did you make sure that none of the orange cables are kinked?

the only thing i can suggest is to try and check that there is a red light coming from the icm, and then into each of the various modules - mini disc/cd changed/phone (behind the climate unit)/sat nav/amplifier (under drivers seat)/sub/antennae module.


(its sounds identical symptoms to trouble i had. 2 dealers diagnosed an ICM failure. But it turned out to be the subwoofer module had packed up. I managed to obtain an "Optical Loop", and then stuck that in place of the sub, and mine now works.)

I have unplugged the fm modulator I tried to install.

I have checked all wires behind the radio and the antenna in the roof and all fiber optic cables are in place.

1 out of the 2 orange fiber optic cables are flashing a light through

here is a picture of the message I currently get from my radio...

if you take the fibre optic plug out of the ICM ( display ) and turn ignition on does it send out red light pulses for a few seconds ? If so its probably ok .
You need to take this to the dealer who is the only source who knows how this works and how to diagnose what is wrong .
