Garmin DriveSmart 86

It is BIG – The first thing to be said about this unit is that it is seriously large at 8" diagonal so it's probably not suited for use in a city hatchback. We have it installed in a LWB van where it's still a fair distance from the driver and doesn't dominate the field of view so it works really well. Most of the 'smart' features we've turned off so it isn't integrated with a mobile phone except for traffic management alerts and all of the nanny features are turned off as well so I can't comment on how well they work. As a Nav unit, it operates very well and the display is clean and easy to read at a glance and the lane view feature (which appears when a decision point is near) is a great feature of most recent Garmin units. Apart from the larger size, it's no better than the Garmin 61 (7") it replaces which only lasted 5 years although the 6" one we also have is still going fine.
