Bests & Worsts Reviews from Amazon

If one follows the instructions and updates the software and Map on a new Tomtom unit before backing up the brand new device, one will be left with a non-functioning unit that must be returned to the manufacturer. The Map update that Tomtom suggests customers download as a matter of course, and which one is prompted to update as a new customer WILL NOT FIT on the device, and the updating process may render the unit useless, as it did in my case. No where is this noted in the FAQ or in Support or on the Web Site or in the downloading procedure or instructions. Having owned literally dozens of software driven devices, I have never before encountered a company that so brazen disregards its customers' well being, by suggesting they download and install a software update or driver that will render the device inoperable. A web search has revealed that many others have had this identical problem, and Tomtom Tech Support is fully aware of this issue. Yet they will not post anything cautioning their customers, or revise the suggestion to download and install the latest Map. I found out the hard way, and will not have a GPS for trip I expressly purchased it for. I must pay to ship the unit back to Tomtom. When/if it works, this is probably a great device. But companies must be responsible, and I imagine that Tomtom will receive many more angry reviews along these lines. Beware.
