Mk3 Octavia - aftermarket headunit installation questions

I did search but couldn't find anything helpful, apologies if this is asked all the time...!

I've just bought a 2015 Mk3 Octavia 'SE' which comes with the OEM headunit shown in the attachment, it has a CD and SD card unit in the glovebox - I'm not sure what the model name is.

I want to swap it out for a double DIN JVC unit I already own, then fit my amps and subwoofer from the JVC.

My concern is that the OEM unit has things like tyre pressure monitoring, reversing sensors, aircon settings, and so on. I don't mind losing the ability to control those via the headunit, a good sound system is more important to me than knowing one of my tyres is a bit flat, but am I going to trigger any warning lights or stop something important working by going down the aftermarket route?

Are there any good guides to doing this? I'm sure others have been through it all before :)
