We just bought an 8" HDS Gen2 for the bow and a 10" HDS Gen2 for the console, plus the weather module (we already have Sirius radio on the boat, so that was a no-brainer). We also got the Navionics chip. They're not installed yet, but I'll post a report once we've had a chance to kick the tires. In the mean time, I've been spending a lot of time watching training videos and reading up on all the new stuff!
