Bet you're dying to go somewhere now. Somewhere far off the beaten track, to see if it works.
Went round the block...and it got me home
LOL... I remember when I first got my nav system fitted I used it to guide me to my folks house from the nearest town centre. Bearing in mind I've managed to walk from the town to their house while drunk enough that I can't remember a single step of the journey, I'd say the nav wasn't strictly necessary
It's absolute bliss though when you want to go somewhere you've never been. Drove down to Warrington with a bunch of mates one weekend for a party, the thing took us straight to the front door with no hassle at all. Certainly beats trying to read directions printed from Google Maps, or worse still read a real map lol. The best bit is, if for whatever reason one of the roads you want to take is unavailable, just ignore the instructions and it will realise you've missed a turn and calculate a new route within seconds. Let's see your Google Maps printout do that
Have fun! 8-)
