I spent an entire afternoon going around in circles like a dog trying to catch its tail & got absolutely nowhere!!! I am trying to connect my device to my computer to update the damn thing, I don't know which device I have, all I know is that its a TomTom Live. Working from the get started screen I have to pick my device from a drop down (120/125/etc.) Trouble is, I just don't know, that's what I need help with. The instruction on how to check refers me to a barcode on the device. I've checked my device: top/bottom/sides/inside & bloody out, & there is no freakin' barcode. So please, help me before I take a hammer to the thing & smash it to pieces!!!
