It is mounted on the car using a suction cup. The sat nav is attached to it with a magnet.

Hello & good evening, I myself own a TomTom Go 620 sat nav, where the Click & Go mount fits really well. I have also heard from friends that this mount fits the TomTom Go 520, 5200 + 6200. Unfortunately, I am not sure whether this mount also fits the ToTom Go 6000 sat nav. There is also a Community portal on the TomTom website. Please register there and ask your question, there are certainly experts who can give you a reliable answer. I hope you get better support there than I can give you. Good luck !
