ICM Infotainment Stereo packed up?

[Beavis]

Hello All,

I've done a few searches about this, and my symptoms seem to differ slightly from others. Wife went out in car yesterday and Stereo does not work. I spent about 30 minutes in it late night (brrrrrr), and have noted the following:

* Stereo button turns the display to "Premiumn Sound System - Dolby Pro Logic II". THis then disappears, and the display unit does not show anything further.
* Sound selector button on the right toggles correctly through the various bass/trebel/front/rear/side-side settings and the display then works.
* Menu button brings up Radio options.
* Phone does not work at all - does not show on display.
* Sat Nav - box under passenger seat sounds like it starts spinning the disc, but the monitor does not rise or do anything further.
* Rear parking sensors do not work.
* Internal lights/reading lights work ok.

THe various threads i've seen have seem to be saying the ICM display needs replacing, but as mine works, i'm not sure if that is the problem.

I've emailed http://www.cartronics.co.uk/Volvo-gallery to see how much they would charge for a custom install, so i can compare against repairing/replacing the Volvo unit.

Any tips or pointers to try would be hugely apprechiated before i have to dust the cobwebs off the wallet....

By the way, car is March 2006 XC90 D5 Executive. i haven't been able to try heating/air con/fridge etc.
Live in Swindon, but prepared to travel in order to get it sorted.

Thanks in advance.

Just been quoted £1850 for a brand new install with DVD/CD/Ipod/bluetooth/parking sensors/steering wheel controls.

don't know which direction to head first.

Local dealer says they'll have to plug in to check codes for £45....another ICE repair company says the ICM's are unrepairable; yet another firm reckons they can replace with a refurbed unit and it would identicial to mine in features etc. Up to £1850 for complete new custom ice install.

Hi Chaps,

Ok, going to have to book it into the dealer for them to plug into VIDA. My local in Swindon hasn't filled me with confidence when i had S60 electrical issues. Can anyone recommend Reading/Chippenham/Oxford for any previous electrical problems?

Would prefer to deal with someone who knows the system inside out.

Cheers

Hi mate your car has what they term a most system the icm is the lead unit it then sends a signal via light down to the amplifier under your seat which depending on your spec it will either go on to the sub or cd player or multimedia player if you have rti fitted. If one of these units receives the signal but does not send the light( signal ) on it breaks the most ring which is when the icm turns off. There are a couple of checks you can do if you remove the connector at the amp which has the two orange wires this is the fibre optics for most you should see red light if you have that move to the next unit depending on your spec of sound system and on until you find where the light is not getting passed on to. You can also just check the fuses for these most units so icm,amp,sub,cd player(mp2),mini disc( if fitted) or rti unit as I say if the unit does not have power it won't complete the most system so the system shuts down most common is the amp as it can get immersed in water and you won't notice until now?! If you need help you can send your details I can guide you along?

Hello Unreal Master tech,

Major thanks for the guidance so far!!

The system i have has amp under driver seat; rear sub; sat-nav; phone; rear park; which i think is all part of the premium sound system.

I've checked:
* front under seat amp - there is definately red light entering the unit, but unable to check on it leaving when the plug is plugged in.
* front sat nav under seat unit - red light entering, but again unable to check it leaving. there is also power to this unit as the yellow lights flash when installing/removing a disc.
* rear sub (looks like a small amp too) - red light passing between the plugs but unable to see if its leaving.

i have also checked all fuses which could relate the the entertainment system in the boot section, under steering wheel section, and side door section and they are all fine. (as an aside when i was checking the fuses i removed one in error and its now thrown a "Anti Skid Temporarily Off" error on the dash now - not my week...

Do you know what route the red light travels around the car from module to module? Any other suggestions or tips would be massively appreciated.

i have been unable to remove the headunit despite trying (its a bit tougher to remove then my S60 one), but will have another go later....

Shame you're so far away (i'm in Wilts), as i'd happily pay you to look at it, and i don't have huge confidence in my local dealer as it took then 9 months to acknowledge there was a software download for my S60 gearbox when they swore blind there wasn't.

Bigs thanks once again.

Hi mate if you remove the panel around the gear selector ( presuming it's an auto you will need to move it to n position to get the panel out) it simply pops up there after you will see two torx screws under the climate unit if you undo these then pull the whole centre stack out at the bottom and slide it down the whole radio and climate unit will pull out this will give you access to the other units which you will now see more fibre optic wiring. To be honest if you have red light coming down the connector at the DVD drive under front pass seat the system would appear to be ok as from memory this is the last unit before the loop is completed by going back to the icm. it would then look like an icm( the screen witch displays radio stations etc ) fault. Do you have access to anyone who code read codes from the car? It's just this system is accurate at telling you which unit is faulty if it is any other unit apart from the icm you can get fibre optic loops which you put in place of the defective unit and allows the system to work with that unit simply being bypassed.

Hi,

I had 4 torx screws at the bottom of the climate control unit. i only tried the top 2, so will try the bottom 2 over the next few days, just to see if theres anything obvious down there.

i'm bracing myself for a new ICM or custom install depending what dealer says.

i've got this reader which is pants http://www.ebay.co.uk/itm/CAR-DIAGNO...item20b3102436 it only gives live reading for the engine, and has not recognised the "Anti Skid" error, or anything to do with the ICM.

Do you know any software which could read the more specialist volvo modules? i've got 2 modern volvos so prepared to invest in something which will no doubt get a bit of future use...

i've been tempted by VIDA/DICE as i believe thats the same as dealer software?? but it only works on an XP machine which is going to be tricky to find.

thanks again.

We use dice in our work with panasonic tough books don't ask what software we run that's not my department am afraid?! I have mentioned on other threads that if you pay for a diag and they tell you it is an icm then your option is to replace it at considerable cost?! Or turn the most security off and try a second hand icm which should work. Your car has a full house on the most system is it an executive by any chance?! The problem is it could be any off these units I reckon if you approach your local dealer for £40-50 they should be able to tell you the fault quickly or you do it yourself but it could take a while?!
