I'm a long time Garmin user so adapting to the Tom-Tom is a bit challenging. I took delivery of my CX GT AWD late May and got the free map update. It's still out-of-date with our recent reconstruction so I bit the bullet and bought the discounted ($39) subscription for 12 months of updates. I assume they release an update 4x per year?
I have a portable Garmin with lifetime maps. Can't complain at all.
Where did you find the $39 subscription?
