Just a bit on the * after ‘lifetime’ from tomtom’s website:
*Lifetime means the useful life of the device, i.e. the period of time TomTom supports your device with updates, services, content or accessories. A device will have reached the end of its life when none of these are available any more.
which to mea means when they deem a device too old they’ll stop updating it and unsubscribe it from live services as well. Still worth the £30 over the 6200 imo. I got the latter and paid £15 to renew traffic subscription this year. If you have it for 2 years at least it’ll be worth the higher price.
Edit: Ah, shullbit beat me to it
