Hi CAtk. You have my sympathy. I’ve had this problem (not the nav switching county and country) for a couple of years and no software updates or trips to Skoda dealers have produced anything other than temporary respites. Radio spontaneously coming on and increasing in volume even when the car is locked and switched off. It’s happened when I’ve been driving too. Info screen going crazy, switching on and off randomly, and randomly showing clock, nav, radio on-screen each time it switches back on. The on/off intervals vary from half a second to several seconds, sometimes accompanied by clicks, sometimes not.
The three dealers I’ve used who have all attempted to provide a permanent fix to the car, and failed, have all said that they’ve not encountered Octavias with this problem before, which seems scarcely believable.
It seems inconceivable that Skoda are unaware that the problem is as widespread as it obviously is from the various forums complaining of this problem. Might it be that Skoda know about the problem but have no permanent solution and are reluctant to admit it. I would be really interested to know if anybody with an Octavia who has experienced these problems has ever had a permanent fix made through software or hardware updates/replacement. My own feelings are that the internal design of the unit fitted in the Octavia mk4 is inherently faulty, so fitting a new similar unit won’t make the problem go away, nor will any amount of software updates, and Skoda know this.
I don’t know if the recently updated new 2024 Octavia mk4 has a different version of the infotainment system, but it would be great to find out if anyone has experienced any problems with it.
It’s disgraceful that Skoda can’t offer their dealers any way of sorting this problem, yet still take money from Octavia customers who keep hoping that the next software update will cure all. My car has had this problem from new, has never been permanently fixed, is now out of warranty, and all future potential fixes will have to be paid for. It cost me £100 for the last failed fix when I was away on holiday!
As I’ve mentioned previously in another post, very high temperatures inside the car, as you might get when it’s locked and in full sun, seem to trigger the infotainment/radio switching on randomly and going berserk. For the past two years, when it’s been practicable, I’ve been covering the windscreen with a reflective heat panel, putting a heat absorbing cloth over the infotainment screen and also leaving the windows open a smidge whenever possible. Not once when I’ve done this has the infotainment system switched itself on spontaneously. Surely this must be a significant pointer to the problem.
I love the car, but wouldn’t ever buy another Octavia until and unless Skoda made the infotainment system utterly reliable and a helluva lot easier to operate on the move. The new Superb has decent controls, why not the Octavia?!
