Make sure to get one with bluetooth, I don’t even know the model number of my garmin but it has big speakers, a mic and is bluetooth, came with a year of traffic and a bunch of other stuff, that I actually thought was worthless but I use it. The blue tooth is suprisingly good but place it close to you like above the rear view mirror or somewhere within reach and not directly above the a/c vents to use the bluetooth. When the phone rings a big flashing phone pops up on the screen and the name of the caller in addition to the ring and if you touch it the call is answered, you don’t need to hang up if the other person does, it hangs up automatically. you can also scroll through your contacts and recent call on the screen, they are automatically transferred with the bluetooth hookup so you don’t need to look at your phone. Even if I know where I’m going I use it for the phone, time of arrival and traffic features.
