Help with Columbus please

[Caleyjay7]

Hi folks,

 

Struggling with a Columbus unit purchased on eBay.  I have a Mk2 Octavia VRS pre-FL (58 Plate) - just removed a Pioneer Appradio 2 to install the Columbus unit.

 

On first installation, I'd forgotten to remove one of the loom adapters unit powered on and produced audio, but wouldn't physically fit on account of the mahoosive hunk of plastic on this adaptor.  One slap of the forehead and removal of adaptor later, unit fits snug, powers on but produces no audio.

 

I've had VCDS on it and enabled Navigation and left Radio ticked, still no joy.  It's coded for no sound system (as there's not one present) and coded for Front and Rear active speakers which reflects the current setup.

 

I've tried disconnecting the battery for 10mins just in case that kicked it into life but no cigar.  On accessing the service menu, I'm not happy with the CAN menu which reads "No connection" next to everything...

 

Any and all suggestions of what could be up would be appreciated.

 

If it's helpful, here's the System output from the service menu:

 

Delivery Part Number: 1Z0035680A

HW-Version: H04

SW-Version: 1024

 

Map info is Navteq West Europe v8048 which I believe is v10?

 

Help please!

v.10 maps on a 1Z0 unit with SW: 1024!

That's one he'll of a mismatch (but I doubt that's causing the issues).

1024 uses 2 partitions (music & maps/POI), v.10 maps uses 3 (music, maps, POI) as the POI's are slightly different.

I'd be very concerned about the 'No connection' issue, but this points to a problem with VCDS (or a serious issue with the CAN gateway).

Not much help I'm afraid, but I'd be reading up on modified firmware for a 1Z0 unit to bring it up to 3810a to make full use of the maps.

Upgrading will almost certainly wipe your map and music and POI data though.

Yeah I expected any firmware updates to wipe all the data.

 

I'm no stranger to updating firmware on various devices but this will be a first on a Columbus unit... Am I able to go straight to v3810a or is there a safer upgrade path through various versions?

[adamal]

You can go straight to 3810a on that unit. I did on mine which was on 1024 and then again onto 4024.

But I never had audio problems and I too doubt it is the recent map mismatch causing the audio error. Definitely worth upgrading the firmware anyway though and it might sort out your problems so go for it.

Had purchased one myself via Ebay.  Found the same problem with the massive adaptor, especially when I got the bluetooth unit separately.  I had to locate the adaptor unit above the air vent, which allowed the Columbus to fit in properly.

 

If no audio, would probably think it's the connector.  Try fitting the original Stream Head unit back in to confirm....?

Sorry, should have mentioned in my original post; I've all ready had the Stream back in to confirm audio works, and does without issue.

Are the CAN "no connection" messages just a red herring? Tried googling that and not getting much back on it suggesting that it's either normal or it's a unique problem to my car...

I'll download that firmware and have at it tomorrow. Need to see if I can find a copy of the v10 maps data somewhere that isn't TPB!

Those CAN errors don't make a lot of sense. Can you see a twisted pair of wires going into the back of the quadlock? That is the CAN connection.

I wonder if someone has fiddled with the main loom to get the old unit to work? You mention with the loom adapators you had sound?

My first suggestion would be to check out the wiring schematic for the quadlock and Columbus. See http://www.my-gti.com/529/volkswagen-rns-510-pin-assignments

Yeah I had sound working with the loom adaptor on.

Got firmware updated to v3810a now, and there is progress even if very slight. I'm now getting system beeps on button presses which I wasn't before. Still nothing from radio or CD though. Confirmed that radio is receiving signal. If I'm getting the beeps would that be an indication that some VCDS work is required?

Just in the middle of putting v10 maps on.

On the CAN no connection issues, I see that the menu is no longer available (or perhaps just needs re-enabled in VCDS post-upgrade). At this time, I'm unable to confirm if the upgrade has sorted those issues.

Once the maps are on, I'll have a look at the quadlock connector.

[Caleyjay7]

Everything checks out ok on the quadlock as far as I can see! Everything is where I'd expect, including CAN +/-

[adamal]

The menu should be there in that firmware but to check in VCDS it is the development test mode adaptation in module 37/56 (that needs to be set to 1).

 

I have a vague recollection of another thread with this issue on here, not sure if it was ever resolved, but worth a search.

Is the Pioneer AppRadio thing an aftermarket headunit?

If so, my guess is that some wires needed to be swapped over to allow the non-standard head unit to get the right connections. Or was that what the loom was for? Was it a pass through loom?

Although if the Stream works without the AppRadio loom adapter thing then it cancels out that thought and points to an issue with the Columbus itself. And not the firmware.

As you can tell I know nothing about this Pioneer thing, so the above is just my musings.

Yep it's an aftermarket HU - http://www.pioneerelectronics.com/PUSA/Car/AppRadio/AppRadio+2+(SPH-DA100)

 

Yeah the loom adaptor or as halfords call it, the wiring harness, produced two ISO connections.  Until I can get VCDS on it again, I can't be sure but my gut feeling is that this is a duff head unit.  If I'm right, I just want to get my money back on it and I'll get a GTMMI HU instead.

I stumbled across a post on a VW forum indicating that my factory fitted Aux connection might be the source of the problem. Going to remove the Aux and the CD Changer from the quad lock connector and try that. When the 3rd party loom adaptor was on, it effectively cut Aux and Changer out anyway.

I have factory fitted AUX and CD changer.

 

Works perfectly with my Columbus.

Yep, didn't make a blind bit of difference.  Still no sound.  Need to get VCDS on it again and look at what options I have.  Thought this was going to be a straight forward swap!

It should have been which makes me think it is a duff Columbus.

Does the Stream still work without the adapter?

That would seal it for me.

Yeah the Stream works without issue.

The only other thing I can think of (apart from broken Columbus) is that the sound system is coded incorrectly.

Check everything with VCDS & try a few different settings to see if they make any difference.

[RainbowFire]

Yeah I had sound working with the loom adaptor on.

 

 

So, everything works with the loom adapter in, but doesn't with the adapter off?

 

Whereabouts in the country are you?

[KBPhoto]

I was thinking that the Stream works without the adapter but the Columbus doesn't.

Maybe I've got that wrong?

[RainbowFire]

Me too, but I was thinking confirmation might be helpful. I have a couple of ideas, but just wanted to check first

Also if he's local there's the option of a MK1 eyeball check over it
