Montie;
We have had a 465T since they came out and I feel it was a very good buy for the money. We recently traveled HWY 93 along the Bitter Root range in Montana and this device gave us all kinds of useful information. When traveling secondary road not only will it give you audible signals something is going to happen, i.e. narrow road, curves ahead, and down grades it is extremely accurate in keeping trip records. Personally, I wouldn't own any other device.
Best Regards,
Jim
