On sale this month at pilots are the RandMcNally 510 for $249 and the 710 for $299. These are great units and mine has never let me down. I'm going to pick up the 710 this week and will have the 510 as a back up.
Thinking about getting the 710. So your 510 has done a good job in the NE? That's good to hear, especially with all the restricted routes and low underpasses up there. Was born and raised in Queens, didn't leave anything behind though, lol. Will be running LTL out of Conover in 2 weeks, thinking about getting one.
