Another thing is updating the built in sat nav. I did this successfully on my Mk3 but it was about as far from straightforward as you could possibly get involving memory sticks, lap top computers, keeping the engine running whilst you download the updates. It's doable but the process has to be relearnt the next time you need to update. It's easy to see why people use google maps or waze on their smartphone.
To add insult to injury, my local dealer charges £114 plus VAT to do it for you - no thanks - I'd rather get lost.
Fortunately I very rarely go somewhere I haven't already been these days. I know some people like and, indeed, need traffic updates but that isn't a major issue for me.
