I recently purchased a mk2 leon fr (59) plate, it has had a double din pumpkin head unit installed by the previous owner. I was just having a few problems with it and was wondering if anybody on here has had any similar problems with a head unit. When I first got the car the head unit was working perfectly fine for the first couple of months, now every so often it will just loose power sometimes it will just power itself back up staight the way or it could be a couple of days later up untill around a week. If I remove the head unit and move wires around to a certain point I can get the radio to come back on but again it could go off again within 10 minutes or a week. Does anybody think it could be a loose connection or could it be a rubbish/cheap wires or canbus device.
Thank you

What make is the headunit? Alot of people fit cheap Chinese clones which randomly stop working due to their poor quality.

It is a pumpkin head unit, I believe it is a Chinese one. They are around 250+ don't know why they would have gone for that over a kenwood or pioneer etcc for the price

Its hit or miss with those units. Some people have no issues at all with them and some have nothing but problems.

It's why I spent £200 on a second hand genuine rns 510 headunit

Reckon it would be worth taking it somewhere to get looked at or just get rid and get a better unit? Do those rns 510 have dab? Thank you

Some of the later rns510 have dab.

Have a look at some recognised manufacturers like kenwood, alpine etc

RNS 315 has Bluetooth and DAB built in, get one of those.

Check the wiring to the existing one first, there will be a converter between the quadlock and the headunit, that could be an issue.

I would test the pin outs from the car ISO connector to the headunit to ensure that the battery 12v and ground cable are working as expected. wiggle the wires if you can with the probes connected to make sure. Then plugin the headunit cable block to the headunit itself and check the voltage at the ACC plug from the CANBUS connector with the ignition on (ensuring that the spare ACC from the car ISO block is NOT plugged into the CANBUS/Headunit ACC wire if you have a CANBUS unit attached (at least for Joying units))

If your car is anything like mine, the CANBUS adapters from the Chinese units are not capable of switching off properly and will drain your battery over a number of days if left in standard issued condition. This has happened twice now, and my battery is currently in my hallway on charge. Interestingly, having just installed the sub this morning, when turning the volume up and down very quickly, the headunit repeatably switched itself off briefly then back on. It wasn't doing this before i connected the sub. This was with the ignition on, but the car not started. Then i tried to start the car and the damn battery is flat again so I suspect my issue is just not enough juice to run all my kit without the engine running (having had the CANBUS drain it for the last week). I have ordered a piggyback fuse tap adapter and will be cutting the ACC wire from the CANBUS unit and using the piggyback fuse 12vACC instead from somewhere in the fusebox.

Having just installed a Joying 4/64 octacore 9" screen (yes it is luuuuush compared to the rather crap and red MP3 standard unit!) using the SPDIF out to feed my processor (the reason for buying this particular Android unit) I have had a few issues which I thought I'd share.

First, the AMP control cable does nothing. 0V always. I contacted Joying who said 'Use our red ACC wire instead'. Why the ***k even include the amp control cable with massive fuse adapter that makes it hard to install in the stereo slot if it doesn't work?? The fuse holder has since been removed and the cable heatshrunk, just incase some evil firmware update wakes it up.

Second, the SPDIF output does not output the Keypad tones, regardless of whether the setting is on or off in the headunit settings. When I contacted Joying about this, they told me in Engerish:

>>>>
1) For the amplifier connecting, please connect our ACC wire with your amp wire.
2)The SPDIF only the sound processor, it is shown the sound effect for the music.
So no matter you connect the SPDIF or not, you also need to connect the speaker wire. then you can hear the toch screen sound.

Hope it will clear for you. if not, please inform.
Thanks
<<<<

Really? connect two sets of speaker outputs to my car wiring?? Four cables from my amplifiers having been fed from the SPDIF signal through a (not cheap) PXA-h701 processor, AND the four speaker cables from the headunit itself?? Are these people *****g insane?? The reason for using the SPDIF is to AVOID using RCA or, worse still, high level speaker output. Sodding Shenzen junk. I am wondering what other sound I might be missing through SPDIF which will be my next question to them.

Having said all of the above, the 9 inch screen, built in 4g sim slot and wifi, voice control over youtube, google assistant, native google maps, the ability to listen to DAB radio, Spotify, Flac files from usb harddrives, The Torque diagnostic app connected via OBD2, Android Auto/Apple carplay (if you want it), and remappable steering controls make this unit pretty awesome.

Yeah il take this one somewhere first and get everything checked, when it wants to work properly it is a good radio the only I carnt use on it at the minute is the navigation due to previous owners taking the memory card with the offline maps when they sold the car. I have got a strong feeling its just due to a wire or something as when I first removed the radio it was an absolute mess behind there, tried to sort everything out as best as I could and have hidden the little box in a compartment above the radio just to make just that wasn't crushing anything. When I first moved it radio came on and stayed on for quite a while then this happened again.also have not had any problems with the battery draining at all yet could be due to the fact that recently I have been driving around more without and radio than I have with one.
Thank you

Thought I would chip in my experience with Android Head units in the Leon. I am on my second, my first was a 9" XTRONS that ran Android 6, my only real issue with it was that occasionally it would lock up and I'd need to remove the fuse F8 to reset, after a while I fitted an inline switch and that was fixed. I really liked everything else about it and just for reference because everyone has this fixation about Google maps I never ever use Google Maps, please drop the idea that Android means Google Maps - it doesn't, I use Sygic and Tom Tom offline solutions because you have the maps on the unit and you never rely on dodgy 3G/4G coverage.
About two weeks ago I bought this unit on Ebay for £182
https://www.ebay.co.uk/itm/9-DAB-St...GOLF-5-6-SHARAN-JETTA-SKODA-SEAT/113328744991
It was advertised as having 32GB storage but it actually has 64GB
Early days but I have to say it is excellent, there is a better solution for what happens when you turn off the car (sleep, power off after a number of minutes or hours) and it was a joy to fit because it is only about 2" front to back and is completely plug and play - the Leon connector just plugs straight in as does the aerial cable with no adaptors required.
I can do a Youtube video if anyone is interested.

I manged to get it to come back on yesterday after playing around with some wires. Hasn't gone off as of yet so hopefully a good sign, think I have managed now to find out which wire it is or the connector the wires go in to. Just got to wait to get paid with it being a 6 week wait to get in to a garage, but hopefully it stays on now and won't need to go garage

Yea, doesn't need coding or anything.

You need a GPS antennae for the Sat Nav to work and a DAB ariel.
Also if your car doesn't have hands free you'll need a microphone.

Nice one cheers mate I'll start acquiring bits for this then. Loving the Cupra only problem is now I don't like leaving it at the train station so looking for a cheap runaround to use for parking at the station lol.

I have now purchased this unit. Would be good to know from you guys that have already fitted if it's just a straight plug and play or any swapping with live feed required for battery drain issues etc?
