I saw so many on the internet thta i don't know which one to install in my vehicles.
My son just got a garmin885,it can be voice activated by pushing a remote that you attach to the steering wheel,or you can manually program it.You can put 10 destinations into it and it will find the best route,plus it has lane assist(really helps when you know ahead of time if it's a sharp right or bear right)highlights the lane you need to be in;fades the other lanes.He bought it to use on his new job driving a beer delivery truck,gets a different route every day.
