De!
Like You I too have been using a portable GPS for a very long time. I bought my first Garmin maybe 12 years ago...
I bought my one I use now about 3 years ago. I LOVE my Garmin. Only thing I wish they would do is enable VOICE ACTIVATED destinations and then show you route choices.
But hey, it is very accurate with auto update on maps for north America and all the places I wind up going to for business are always there. Great GPS.
My car has a built in one and I also have a downloaded APP on my cell phone called WAZE.
It's free for both Android and Apple.
It has a feature that if you get stuck in traffic or something, it can show you a detour around the mess and not sit in it...
It also shows you bottlenecks and construction ahead because other WAZE users have reported it and it shows up.
Nice APP to have on your cellular phone....
I just prefer looking at my Garmin.
Great choice!
