Question: how do you select dirt roads
Document: For example, I was looking to avoid toll roads the first time I used it, and there is no on-screen option to do so when you select your destination. I ended up driving in the general direction of my destination and passing all on-ramps to the turnpike until there was only one possible way it could take me.
I like everything about this unit. Sure the suction cup comes off once in a while, but GEE - Garmin doesn't make those things! You can set it to "avoid" things like dirt roads, HOV lanes,U-turns, traffic, ferrys, etc, but you have to read the instructions first.
My first real test, which the Garmin 2460 passed with flying colors, was on a trip to a remote plant site on the Roan Plateau in NW Colorado. The unit found all the dirt back roads and took me to the front gate. It also got me to an obscure medical supply place and Asian Market here in Denver. This has the best HMI (human machine interface) of any device I own, along with my keyboard Kindle.The features work extremely well that I have tried.
I selected yes and a small blue triangle icon was placed on my top-bar. You are able to configure the updater as off or on for automatic mode, and select the time period for downloading or choose any time.Finally, completing this process, I had to disconnect the Garmin from the computer.
You can also switch the icons around by dragging it and that icon will get switch to different location of the menu.After you customize your screen, you have to go back into Tools>Settings>Main Menu>and select "Use Customized" then you will see all the short cuts you created appear on the main menu display.This is when I get upset and suspicious after I select customize my main menu.
My c340 took way, way less time than that to boot up. This would be less of a problem if voice commands actually worked and you could effectively select destinations while moving.I like that this unit doesn't say "RECALCULATING!" in a scornful voice, but I wish it had the option to turn on some small alert to let me know I screwed up and should pay closer attention.There is no external, physical volume button.
I had the first Garmin Nuvi 6 years ago and was very familiar with Nuvi features. This one is better in that it pronnouces the street names that you'll turn into. The highway sign assistance screen came on and off too quickly to be helpful. I tried to select options such as highways only, avoid tolls, etc. but could not find them. Selecting the "Fastest routes" in driving from northern VA to NC, the GPS took me through towns, traffic and so many traffic lights.
On the Garmin it was working very rarely and only on main roads. On the Tomtom my experience has been better.
It takes close to a minute to load the maps and be ready to navigate. As with any GPS the routings sometimes are a little odd. It sent me on a roundabout way instead of the more direct route. It knew the roads were there but didn't route on them for some unknown reason.
I have the Iphone 5, while I occasionally use the phone's GPS, having the Garmin makes such a difference. The traffic function only works on major roads. All in all, having the 5 inch screen makes it so much easier to use.
Answer: If you have an ending point that requires you to drive on a dirt road. It will direct you that way. Other then that I am sorry I don't have an answer for you.
