Possibly but the 51 is designed to enable you to use a linked smart phone for traffic https://buy.garmin.com/en-US/US/p/111441
It will provide digital traffic, a far better service than the FM based traffic on your 1390.
Thanks. Another feature I miss, or perhaps there is a way on the new garmin is the track history. The old device would show lines on roads I have been too. How do I get this feature to work on the new device?
