I use it the Skoda sat-nav in preference to Google maps, but that said, for the vast majority of my journeys, I tend to know where I'm going. I don't use sat-nav enough for any clunkiness in the user interface to be a nuisance.
Entering an address in the Skoda system isn't as easy as Google maps, especially as you can use voice control for Google maps, which is really handy.
The voice control on my Skoda is rubbish, which considering it's a 2019 car, is a big disappointment.
I'm not a big fan of Google Maps, which I find tends to give very poor instructions.
Example: Google maps tells you to leave the M42 at the "Bickenhill Interchange". What it means is Junction 6. There is no signage on the motorway that tells you junction 6 is the "Bickenhill Interchange", so it's a poor instruction.
Obviously it's clear on the map, but it's a silly mistake the Skoda sat-nav doesn't make.
I've also found Google maps gets confused on some roads under certain conditions, but that may be down to urban conditions affecting the satellite lock. Whatever the problem, my Skoda system is more dependable.
I've navigated a journey with both Google and Skoda sat-navs running, and I found the Skoda sat-nav gave more timely instructions than Google maps.
If I could only use one system, I'd choose the Skoda system. If I was a delivery driver, I'd probably choose the Google system, as the voice control is so useful.
