Summary: The size of the map files are getting bigger, to the point that they can no longer fit in the internal memory of the unit. They now have to be stored on an SDCard. If you search TomTom website, you can find the recommended card size, I think it is 4G as of September, 2014 I messed the unit up some how, found a web page how to install from scratch. Whatever new software that TomTom installed renders the touchscreen inoperative.
Summary: This product had problems right out of the box, the Bluetooth is a joke cause the mic on the device only picks up ambient noise. Called TomTom customer no-service and was told I could send in my brand new device in exchange for a remanufactured one. I told TomTom to kiss it. The "free traffic service" that was included with my device was taken away during a device update to TomTom Home.
Summary: First off voice input is a joke: you have to press loads of buttons to get to it anyway! This satnav is my first though I've used my boss's simple garmin lots over the past few years. I went with this one beacause of IQ routes and Lane Guidance but these are totally irrelevant when you realise how bad it's maps are. I live in North London an area you would expect to be well mapped but no, TomTom has no idea of loads of 'no left/right turn' signs or 'one way' streets.
Summary: Ein neues Original verpacktes TomToM 730 Go Traffic war gleich zu Beginn defekt. Es ließ sich trotz ausreichendem Batt. Laden und wiederholtem Reset-Taste drücken nicht starten. Der TomTom Service (wenn man mal die Tel.Nr. gefunden hat) ist aber sehr um Hilfe bemüht, es wurde auf Veranlassung von Service TomTom Aachen vom UPS-Paketdienst abgeholt und soll auch wieder retourniert werden. Ich bin mal gespannt wie lange das dauert!
