Whenever I start the car the welcome page on the information and “loading the user profile” takes a good 30s sometimes. It’s only me who drives the car so I’m not sure what it’s doing. Any advice?

This link is to the results of a SEARCH on "user profile" across all the BRISKODA forums.

My 2024-built Fabia Mk4 also has the Amundsen infotainment unit that's fitted to your 2023 Fabia and I'm my car's sole driver. The Welcome/loading user profile... screen always appears at start-up and, when I press OK, that 'command' is normally accepted with minimal delay.

My understanding is that having the Welcome/loading user profile... screen-display on the infotainment unit at start-up is unavoidable. In your case, if loading the user profile takes a maximum of 30 seconds but only sometimes, and if, once the user profile has loaded, your car's Amundsen unit works satisfactorily, I suggest you take an "If it ain't broke, don't fix it" view (or "Grin and bear it")

If your 2023 Fabia is still under warranty, you could seek advice from a Skoda dealership to see if there's a software/firmware update that might speed up the Welcome procedure, but I'd be VERY wary of attempting a DIY 'fix'. Shortly after buying my new Fabia Mk4, when I was playing about with the car's display-screen menus, I accidentally triggered a factory reset. There is advice in the Fabia Owner's Manual about the Amundsen unit and 'User management" and (eventually) I was able to recover the system and reset my user preferences, but I wouldn't want to have to do that again without a very good reason.

Yesterday I had the welcome upload and then my music came on only it did not have e a volume control slider on the screen, why?

My car is a Mk.4 SLE .

I notice that you had problems with your car's infotainment system (MFD) in June 2025

Issues with the MFD were also mentioned in this September 2024 forum discussion

and there's a lot of criticism of the system in this Fabia review.

A GOOGLE-search on skoda infotainment system glitchy will confirm that the type of (usually transitory) problem you've mentioned is not confined to Fabia Mk4 cars.

My 2024 SE L Fabia's MFD system occasionally 'glitches'. There's no point asking why - it's a complex unit and sometimes it gets its multi-function knickers in a twist. So far, turning my car's MFD off and on again has restored the system to normal operation.
