Have any of you guys updated just the AT2 with the new software but held off on updating the mfd? If so does the AT work like it should? I’m wanting to update both of my AT2’s but not wanting to do the live units just yet. I’m fishing a 2 day tourney this weekend and wondering if I should go ahead and do the AT’s or just wait until I get back home. I am mainly wanting the new range adjustments that are 5 ft marks now instead of the 10 ft it started with out of the box. I know when I update them I cannot roll it back at all because there was never a base load available to have as a fall back like with our older live software.
