there are two main things that purchasers need to know:1) space is very limited on the device.there is only 2 GB of internal flash memory and out of the box there was less than 50 MB free.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.
after removing spanish and french voices, running update which installed a new dave voice, and then installing the free map update i was left with 89 MB free.
when i tried to run update before removing the voices, the unit warned me about lack of space and aborted without creating any further problems.
just received my new GPS today, plugged it into my mac, and installed tomtom's mac version of their home software.
everything has worked well so far and the free map update installed fine.
No where is this noted in the FAQ or in Support or on the Web Site or in the downloading procedure or instructions. you can back up then delete all foreign computer voices (recorded voice files are small, so doesn't matter).
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. just keep DAVE, and Susan computer voices( you need at least one computer voice for spoken street names). after you're done, you still have 125 Mb extra to download customized items, map corrections in the future.Well, OK, we figured that we at least had the original map available and would work with that map.Come to find out, the download process wiped out the original map.I found out the hard way, and will not have a GPS for trip I expressly purchased it for. I chose Tomtom over Garmin mainly due to tomtom HOME support, better user interface: tomtom has more info on the screen including the street name you're driving on. Pros: 4.3 inch screen, great routing, advanced lane guidance (it does work well), IQ route (faster route based on historical traffic data), very quick GPS fix 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.Most negative reviews here are from issues updating map which is larger than the old one (about 5 Mb larger) and causes it's simple to go around it.1. 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.I was told that yes the updated map is alot bigger but if you go into your tom tom home application on your cpu and delete a couple of those silly voices that we never use first. Remember, you always have the option to re add those voices later from tom tom home.
