Is the HU-850 coded in any way?

izools · Apr 24th, 2021, 16:56

Just gave dad our 2006 S60 SE Lux and it's fine except for the stereo having developed the popping sound rather than actually working.

I don't want to send the HU off for repair, I'd much prefer to buy a working HU-850 and replace it for him.

Are the HU-850s coded in any way or would I be OK to buy one off eBay and just swap it out (while battery is disconnected)?

I have the necessary tools to clear any SRS codes that come up as a result of the swap but that's about it.

Oh, it's OK, found out already...

No code, just gotta make sure to find an HU-850 from the same model year otherwise funky stuff can happen with the display and steering controls.

Order placed, fingies crossed!

I may be wrong but as far as I know, the SRS fault only happens when you remove the heating controls. you can just about twist+swivel them out of the way instead of disconnecting them.

unplugging the cig. lighter is ok if necessary. also, point to note, good place to hack in and hijack 12v for a dashcam

I have carried out the removal and refitting of the HU850 several times.

Turn the ignition key to position 2, disconnect the battery and then get stuck in. I was fortunate enough to find a working unit after asking on the T5 facebook page, I have no idea what year car it came from but it works perfectly.

When reconnecting the battery ensure the key is in position 2 before reconnecting.

The HU850 is really easy to disassemble, if you are handy with a soldering iron the popping fault isn't a difficult fix, if you are a hamfisted oaf it can be challenging.

It's a shame really because when I took mine out I just dumped it, I should have put it on Ebay I suppose. I didnt really think anyone would want it .. oh well live and learn

edit: mine was an older type with tape deck

Easy fix

Swap your multichanger into this unit or put the pcb from this unit into yours. It is easier to swap your changer into this one or fit this one with a grom or similar.

Thanks for the replies guys!

Yeah I had encountered that YouTube video before and I had disassembled my HU850 a while back before giving the car to my father, but didn't proceed with the repair as I could see no signs of heat damage or dry solder joints like the fella in the YouTube video clearly saw.

If anyone would like the old HU for the cost of shipping once I've swapped them to try the repair yourself let me know 👍

I will be happy to take you up on your very kind offer.

I do enjoy a challenge.

I will come back to you once I have swapped the units over, this will be about two weeks from now 🙂👍

I have a 2006 v70 with a duff 6-CD player, keeps ejecting - I think the motor is faulty - it got hot on the drive to Spain this year.

Does anyone know if all the CD (NOT RADIO PART) units are interchangable?

Anyone ever repaied one?

Anyone got a HU-850 for sale - even with a faulty radio ? Thanks
