I got my TTGO720 approximately 20 days ago from eBay. There is a card included in the box ?Last Map Guarantee? so I tried to download the new version 715 of North America. My map is only v705. I connected the device to TTHome and it said that I have the latest version of the map. I called TomTom tech support and spent with tem maybe 2 hours. They asked me to upload proof of purchase even the document included in the box said: ?Offer valid 30 days from the date you start using your TomTom GO 720? - this means not from the date of purchase. They did not want to accept that and said that TTHome would automatically download my new map is I would used it for less than 30 days. I could not believe that and went to buy another unit to Staples. Connected it to TomTom Home with the same result ? no new map available even I had the v705 on a brand new unit. Call tech Support again and they said that they do not recognize invoice from eBay as document for ?Latest Map Guarantee? because I would purchase it from the third party. Does not matter that the box was sealed, does not matter that I have not used the device for more than 30 days and have the right, according their card and web site, to get the newest map. I was disappointed and do not recommend TomTom because of their tech support.
