An Interesting Day with 7200

I've had a trip like that. Got mad at Jack, then went to Karen. I, too, had it on shortest distance rather than Fastest. Switched to fastest, and all of us got along much better. That was one of my first trips, but I have learned a lot since then and things have gone very well since.

Jack does tend to get a little PO'ed at you every now and then, doesn't he? haha.

I won't have my Nuvi until tomorrow (UPS called to say it will be delivered - finally!) but I long ago learned to select Fastest rather than Shortest for my route. When geocaching the shortest route may take you over the top of a mountain on a something that is loosely termed a road. "But it's only 11 miles this way and 24 miles the other route" doesn't mean much when the 11 miles takes 2 hours to drive.

I'm sure I'll have some "arguments" and adventures of my own learning how to deal with a new type of unit. I'm so used to the 76CSx that the Nuvi is going to be a completely different experience. I often ignore my route on purpose and my current unit will trill at me over and over as it recalculates. Hopefully the voice on the new unit won't make me any crazier than I already am.

Yep, I learned about the fastest and shortest on my first trip. Now I keep it on Fastest.

The shortest was shorter by 2 miles, but you went through stop lights rather than straigt Interstate, so it did take longer.

When I drive to my in-laws, who live 13 miles from us, it will always want to take me to the Interstate, but I know it's not fastest all the time due to traffic jams and stuff, so I just let Jack or Jill tell me they are recaluculating a few times.

We just recently purchased a Nuvi 750 as I do deliveries all over the state of AZ. I also deliver to Southern California and will probably take on stops in western New Mexico as well. I drive a 3/4 ton pickup with a 25ft enclosed trailer behind it.
Just after purchasing the Nuvi my wife and I went away for our anniversary to the Pinetop/Lakeside AZ area where we like to do a lot of off-road travel over the forest service roads. We had Jill pretty confused a lot of the time but learned that in order for her to not direct us back to the main highway we had to change her to shortest route. Of course we never take a trip off-road without our atlas of back-roads in AZ (The AZ Gazateer) so we could compare the roads Jill was telling us to take with what shows up in our book.
We had a lot of fun frustrating Jill and confusing the heck out of her but considering where we were and what we were asking her to do for us she actually didn't do a bad job. Sure she might tell us to take this 4x4 Ram Mega-Cab up that hiking trail once in a while but she only squawks for a few seconds while she frustratedly tries to recalculate a new route.
After getting back to Phoenix, she does much better a;though I do switch back and forth between fastest and shortest routes. I also frequently change the avoidance options to select No U-Turns as my truck and trailer combined are about 50ft long. I also had to rename Jill to Jack as I could not handle some of the gross mispronounciations she comes up with. Jack seems to do a much better job. And for some of you 4x4 lovers out there, the route setting of off-road does not mean it will select 4x4 roads... it seems to be designed for walking.

I learned about U Turn avoidance the hard way. I wasn't sure where I was headed and went across a highway instead of turning left. (My unit was just starting to calculate and I didn't want to hold up traffic.) Once across the highway I was directed to travel 14 miles, turn left, turn right, turn right, turn right yet again, travel the same 14 miles back to the highway, and then turn right. The end point was only 2 miles from where I should have turned in the first place. I no longer have my unit set to avoid U Turns.
