I prefer to follow the advice of the professional vehicle technicians I worked with at a major automotive consultancy than any internet posts - so for me it will always be negative first (and as a Chartered Electronics Engineer it makes no difference how capacitors discharge when the circuit is broken by disconnecting either battery terminal).

That means there is no sat nav signal being received, so the people who say it's a GPS aerial problem are spot on IMHO. If it was a map problem then it would show you on a blank background if the GPS aerial was OK. My Amundsen has an option to show how many satellites the GPS is receiving, your Columbus should have that also - I would RTFM and check that before doing anything.

... the bodywork?

If you've ever watched a video of a spanner being melted by a car battery then you'll never undo the positive terminal first

Even Skoda dealers get it wrong, I had to tell Marshalls Barnstaple that as the water pump is on the other end of the engine on my 2015 1.4 I didn't want the water pump changing when they replaced the cambelt last year.

The MY usually starts when the factory returns from its summer break which is in July - this allows the changeover (and any modifications to the production line) to be done while the line is idle. I had a 2007 MY Audi that was built in June 2006 (and delivered to me in July 2006) - so sometimes they can build new MY cars even earlier.

That's the old 3-phase colours that were changed many years ago - including making black one of the phases as shown in Phil-E's post (L2)!!!

If it was built after around May 2014 then it would have been a 2015 model even though it was registered in 2014. Check the model year digit in the VIN - this is VW details but the model year still applies to Skodas VW VIN codes

The message isn't saying anything about the maps not being found so I don't believe the SD card is the problem, the message seems to suggest that the unit is thinking that navigation isn't enabled which to me suggest an intermittent problem in the glovebox unit itself.

So 1803 will not be a fix for those with C versions or earlier. IMHO this means that Skoda UK should be paying for the hardware to be updated to the latest E version on those cars.

Why have you asked for a 'belt' to be fitted? Which belt? As you correctly say on the 1.4 the timing belt is on the other end of the engine. If you have had the timing belt replaced according to Skoda UK's recommended 5 years that would have been in 2019 so replacing it again would seem unnecessary IMHO.

Baku could be interesting if the suggestions of protests about the flexible rear wings actually happen.

Yes BUT: 1) you'll need to change the USB cable to the CarPlay compatible one 2)you'll need to have Component Protection removed and the SWaP codes re-enabled (both of which need a connection to the Skoda servers), then you'll need the coidng and adaptation checked to match your car

There are two issues at play here: 1) Kopacek (new name for Superskoda) will only ship to the UK using post not couriers, so there is a size and weight limit. 2) post-Brexit HMRC apply the value test whether to seek customs duty and VAT. So small low value items it's the same as before, small high value items you will have to pay duty & VAT, large items Kopacek won't ship to the UK.

Changing just the screen won't add sat nav, as already said the screen is JUST a screen to add sat nav you need to change the unit in the glovebox to an Amundsen - and check the compatibility of the screen with that new unit.

There are 3 different specs of BCM so some 'tweaks' need the medium or high spec BCM which isn't fitted to all Octavias - the tweaks seem to be accepted when you change the settings using VCDS but because the lower spec BCMs don't have the hardware don't actually work!

CarPlay and Android Auto need a USB cable connection, they won't work via Bluetooth - which is only for hands free and music.

It is - there are 2 camera types fitted the 'full feature' A5 (which as you have LDWS you will have) and the 'poverty spec' 20 (which my Octavia has and that only supports HBA). Both these cameras are mounted in the windscreen behind the interior mirror - BTW they are not the same thing as the BCM (Body Control Module) which is mounted behind the glovebox.

OP says he has a Karoq in his profile, but is posting in the Octavia 4 forum?

TDI or TSI?

Might be better to ask that question in the Mk3 Fabia forum instead of the Mk3 Octavia forum?

... or the car in front slow turning off to the left - this has happened to me several times and is the Front Assist working correctly (if slightly 'crying wolf'), all you need to do it just tap the brake pedal and the warning will go away. It's the safety system on the car warning you of the need to take some action to prevent a crash, it's not a fault it's correct normal operation.

When you replace the glovebox unit Component Protection will become active - removing this needs either a friendly dealer or an independent with access to the Skoda servers, on top of that any features that require a Fec (Feature enabling code) will need re-enabling - again needing contact to the Skoda servers) and finally the coding and adaptation channels will need restoring to the same values as the original unit.

Certainly sounds like the Front Assist warning to me - not an ABS issue.

If it's the SD card for your navigation system then we need to know what system you have - the Amundsen only works with a genuine Skoda SD card but for updating the maps on a Columbus you can use any SD card. As you have a 2014 model you will have a MIB1 system not a MIB2.
