Here in US, after connecting my 740TM Live to TTHome via my computer this AM and letting my computer download "upgrades" (traffic, fuel prices, mapshare,etc) instead of trying to sell me "Simpson" voices alert popped up giving me three subscription options for live services: 1yr, 6 mos, 1 mo automatically renewing. My 3mos free trial ends like yours (interestingly) on 8/28.
But I decided to bite a cheap bullet, and picked the 1mo automatically renewing, quit at any time, for $9.95 monthly. As instructed in confirming email, logged onto my TomTom account and once all that worked, went back to live services button and found that my new subscription end date was 10/27 instead of the expected 9/27. But I have two thoughts: (1) Will be interesting when I check my online account tonight to check CC transactions and see if I only paid $9.95 and got 2 mos, and (2) whether I get stuck with a foreign currency transaction fee since the first line says "Payment of your order has been processed by Bibit and will appear on your account as Bibit BV."
