I've got a Garmin Dezel and trust it mostly. I do watch it and make sure it's on point. Had it updated at there home office and type in ATF and didn't show up. Google pulled up two in that town. Took it back in and showed them and they were shock, LOL. ATF was only two tenths of a mile away. LOL
Quite often if I couldn’t find something on my Dezel, I’d find it on Google Maps. Then I’d notice that 4800 Rt 42 is actually 4800 Main St. Or 1210 Wayne is actually 1210 Wain.
Dezl does much better once you put in proper info instead of what dispatch gives you.
