? About my new Garmin 780, low bridges and routing?

Good question. I’ve only had mine for a few months. But, I have it set at 14’5, and it has still tried sending me under a 14’3 bridge.

 

800 number or an online help come with it?

 

I have had mine for roughly a year and the smaller screen version of the dezl for about 5 years. I sometimes run tall and it has always been accurate for detours around the short bridges. Maybe you need to update it online as I had to do so when I first got it to get it to recognize newer roads that had recently opened.

 

I bet yours has some setting that isn’t working correctly. I called customer service and they were knowledgeable about mine. When I first got the old one I drove around my city in my pickup and it caught every low bridge I went under. Occasionally I will try to trick it by changing my height and it always will reroute me.

 

My 780 didnt even warn me about a 11'6 train over pass and it was set to 13'6

 

Try running an update on it. I believe Garmin recommends updating it once a month even right out of the box. This requires hooking the unit to your laptop or PC, and creating a free Garmin account.
