Amazingly my ten year old Tomtom still gets free updates - it was a good £90 worth.
That's good to know. We still use ours (similar vintage) but I long ago lost the instructions. How do you update it ? A few weeks back we found ourselves spectacularly lost in Reading, as the supermarket car park we kept being directed to wasn't there when our TomTom was born. (Don't tell me to check on the smartphone, we haven't got one !).
