Used to have a tomtom, as far as finding out where it was, hard to fault, point to point navigation? again pretty good.
however I bought it for the traffic infomation and the ability to route round trouble on a somewhat long routine drive.
the service where it connects via my phone was ok(ish) but could get expensive with data charges, so I got the antenna to allow it to pick up over the air signals.
which basically didn’t work, well it did in one location, the rest of the time it lacked a signal.
oh and the device had a tendancy to crash a few times a week, ok easy enough to reset with a paperclip but not while driving.
tech support didn’t help much either, I was told the traffic info would be useless in ‘the middle of nowhere’, to which I did try to explain the M1 in the UK isn’t the middle of nowhere.
as for thr crashes apparently I just had to put up with them since it was a ‘pocket pc based device’.
i took it back, argued a bit and got a refund.
I’d have another if:
1, there was a way to set a given road, at a given time of day has an average speed of ‘x’, thus I can program in every day trouble spots to avoid.
2, the traffic warning system actually works out of the box.
3, its somewhat more stable
nice tech, give it a few years and it will be very good, from the looks of this arrticle its getting there
