Ferrites didn't work. Plugged a 1v charger in, didn't affect radii. Plugged what I think is a 2.1v and the music cut out. Plus, if I have a battery pack charging my phone, no problem. I'm thinking less electrical interference now, but maybe there is an issue with power supply. Must check the load capacity on battery with multimeter or something.

I've ordered and fitted a bunch of ferrites. I've got one on the fuse tap, and one on the whole power cable of the hardwire kit. I've then fitted one to the dab aerial plugged in, and one on the original dab aerial that isn't plugged in. The radio was still cutting out, so I added another ferrite to the end of the hardwire that plugs into the camera. And it's still cutting out. As I understand it the ferrite changes the frequency of the electric signal. Whilst typing this out, though, I realise fitting a ferrite to the power and the dab, I've probably changed both of them to a similar frequency now. My next step will be removing the ferrite from the dab aerial(s?) and see if that fixes it.

If nothing is plugged in to cigarette ports, and I disconnect the power cable from the camera, but leave the hardwire in, radio seems to work a treat. When I rebuilt the stereo I bought a battery charger which measured voltage at 12-14v so I'm sure my battery is ok.

Evening, all. Bit of a strange one, but I'm having some interference on my dab radio from either one of the cigarette lighters, or a hardwire for a dashcam. A few months ago, my stereo (Columbus) went odd and resulted in me replacing it with a lesser model stereo. One thing or another, I spoke with pab (thanks, again) and got the firmware to rebuild the original stereo and it is working a treat. The Columbus stereo does this thing where it just cuts out digital radio signal. I wired a new DAB aerial onto the windscreen, thinking it was a water ingress issue with the fin. It got slightly better, but not gone by any means. (Runs behind the glovebox, up through the column on nearside, then sticks on the windscreen near the rope of the window) It only cuts DAB signal, not FM and not Bluetooth audio. When I changed to the lesser model (Blaupunkt VW radio) this interference was gone. The radio, though, lost access to a ton of radio stations with the latest DAB upgrade including Absolute. This is why I decided to rebuild the Columbus unit. When I refitted the unit, the interference was gone. I'd put it down to a firmware bug, which led to the demise of the stereo in the first place. Well, since then I've fitted a hardwire kit for a dashcam. All seemed to be working fine, still. Over the last week, however, the radio has been cutting out (not going off completely) and unplugging my dashcam has resulted in this stopping. (Hardwire kits runs from fusebox next to steering wheel along the column, runs along the top of the windscreen hidden beneath the trim, pokes out by the rearview mirror) I'm right royally confused by the whole thing. Hoping someone will go "Ah, yes, that'll be......" I did pop it on a cheaper OBDii unit before the firmware rebuild where the stereo cut out but obd showed no errors.

Worth a shot, I guess. I'm borrowing an endescope to look in the bulkhead, try and find the missing bit.

Damn, that sucks. I don't suppose you still have that connector, do you? 😆

Hi. I have one of these that has disappeared, and was looking to replace the bit. Seems pointless to buy a whole new unit. Did you order just the missing bit or a whole new vent unit?

Hi, there. Sorry to resurrect this post after a while, but I may need something similar. Got in the car last night, radio "working" but no sound. Whatever channel, or input. Nothing. Reset the infotainment system. Left it a few hours. Got in and audio! But only one station, no volume response. Switch ignition off and radio stays on. No power button control. For now I've unplugged at the back so no power, but most frustrating. I thought I'd got a hardware disk but it only seems to be the satnav, not audio. If anyone can help, I'd be most grateful. I do have a cd burner, although I probably need to get some disks.

I've "resolved" this issue by fitting another DAB aerial to the front window. It currently isn't raining, so I can't test, but I can't think what else it would be.

Anyone?

Hi all. I've seen a lot of posts on various issues people have with the Columbus units but I can't find a direct comparative for my issues. Hoping some of this will make sense to someone out there. I bought a MK2 Superb estate, 2015, recently. Head unit is Bluetooth/Dab Columbus. Radio signal is intermittently sketchy asf when I'm driving. I had the unit out and all plugs are connected. Tested it with the cigarette lighter not connected in case of external electric interference (which I'd seen a lot of advice on) All fine. Wondered if there's a loose connection around the aerial or something. Been looking at connection settings and it showing dab aerial active and quality good. Which is what then lead me to possible connection in roof. This messing weirdly seemed to give some stability in the signal when driving the other night. I put the rear window heater on, though, which cut out the signal. I had the aerial disconnected icon on dash, but signal screen was showing muted. So it appears, to me, to be electric interference from the somewhere. Couple of days later I was listening to dab and the signal was fine. No interference. Later that day, it was raining and the signal was sketchy asf again. Thought back to when I first discussed this and it was raining, heavily at times. From reading lots of posts on here, I've come up with a few ideas: Is there water ingress around the aerial? (No sign of leak on the roof liner) Is the dab aerial fitted in the rear column by the boot, so the heater coming on caused a short there? Would fitting a separate DAB aerial be easier than trying to potentially repair the other (wired probably through the dash and mounted on the front window). I've tried to contact a friend of a friend who's an auto electrical specialist, but he hasn't come back to me. Just trying to figure this out. As a secondary matter, the Bluetooth doesn't connect to the head unit every time I switch the engine on, but appears to be connected via the heads up display. Only happened 2/3 times in 3 weeks. I wonder if the unit is having issues because of the other prevalent issue, so I'm trying to fix that before I look at this. I have purchased a dvd setup disc to try and reload firmware (if I need to). Any advice please would be greatly received.
