No - definitely YANBU. I adore mine too - I used to drive lots in my old job and navigating with printouts from google maps is horrid. The best bit is the way that if you miss a turning it just sorts it all out for you...
My SatNav is completely bonkers, but it's one of those that's built into the car itself, IYSWIM?
For some reason once it works out how to get to wherever it is I've asked for, it always proceeds to tell me loudly, 'the route selected involves a sea crossing'. Having taken the risk and trusted what the dahboard tells me once we're moving, I've learned that a sea crossing isn't always necessary when travelling around Yorkshire.
YANBU to be in love with a clever new SatNav at all.
OCD its a Tomtom Go Live 1000. It truly is a thing of beauty. And clever too. The traffic jam bit is so clever it shows you exactly where on the road the slow bit starts and ends and how many minutes it will delay you by and if there is any way round it. It updates every couple of minutes. None of that on the old one.
