So color me stupid, but what are the/are there any differences in the Gen 1 and Gen 2 units? Better resolution etc? I’m in the market for a new unit, and found a nice deal on a Helix 7 Gen 1 SI unit, but was wondering if the Gen 2’s were THAT much better. FWIW I’m probably not going to be able to afford the SI in the Gen 2, and was looking at just going with the Helix 7 DI/GPS combo to better fit my price range. Thanks in advance!
