Bests & Worsts Reviews from Amazon

Purchased this item after a trip through Europe as a replacement / upgrade for a Tomtom Via - which served us well on our trip despite a failed internal battery (that Via was a replacement for another newly purchased Via which could not hold the needed memory expansion card). Anyway, despite an awkward user interface, this GO 620 has many desirable features - most of which we did not have an opportunity to try out since the item failed in a couple of pretty basic ways prior. First, downloading maps and system updates (which you are requested to do immediately - and which you will probably need to install a memory expansion micro-sd card to complete) was a stressing challenge. Updates are to be done via wifi or usb connection to a computer. Took me 1/2 day to successfully download US, Canada & Mexico maps (usb consistently failed but was finally successful via wifi). Was never able to download Europe maps at all using either method; kept getting message "Oops Something went wrong. Please try again." No success at all after many attempts so initiated a case with tomtom tech support - who have been completely unresponsive for 3 days now. Second, we tested this GO 620 an a trip from our home in NM to a restaurant in El Paso, TX along a route with which we were very familiar. Used our older Garmin to compare. The Tomtom was trying to take us along some really bizarre routes which were completely illogical. Our trip from El Paso back to home in NM was pretty much a 45 mile straight shot along I-10. We set the GPS preferences to take us along the fastest route (umm, that would be along I-10, yes?). Nonetheless, the GO 620 repeatedly tried to take us off I-10 onto some farm roads - and then, amazingly, back onto I-10. Go figger! Bottom line: can't download your maps, can't get reliable route guidance, can't get responsive tech support - in short - you can't get what you expected and paid for. 3rd Tomtom product going back to Amazon. Very disappointing!
