Best to buy from a European source as the frequencies the US one use are not in OFCOM’s approved frequencies for use in the UK and some are used by UK emergency services. The EU versions use the EU approved frequencies and these have not changed for the UK since Brexit. Whilst a US item will work in the UK, it’s illegal, may result in interference to emergency services if you are in range and, if you try to update the software, Garmin will lock it.
