Is it worth to spend 30 bucks on Garmin lane assist?

-No. Also worthless is the 3D building view and built in FM traffic receiver, which are all on my 765T. Purchase the least expensive Garmin and get a new one every two to three years. Cheaper than constantly upgrading maps.No. Also worthless is the 3D building view and built in FM traffic receiver, which are all on my 765T.
