I assume there are some OTR truckers on here. Any suggestions for a new GPS unit. My boss has an older, smaller Garmin that is probably 5-6 years old and he wants something bigger and nicer. I see offerings from Garmin, Rand McNally and TomTom, but they all seem to have a lot of negative Amazon reviews. Any first hand experience on what is out there that is decent? He would like to find something in the 7-8" range, bonus for a built in or optional dash cam. Even more bonus points for some sort of built in ELD option for his logs.
