Well I just picked up my new 60CSx and have been playing with it for the last couple of hours. I also got the NZTopo maps (all purchased from Kiwitonita) and am suitably impressed.
The detail is incredible and a lot more than I expected. The open source auto-routing maps are great as well - I still can't believe these are free! I just now have to decide if I need the BlueWater charts for plotting those cray spots!
Thanks to Tony for showing me the ropes and for his great little 'startup pack'.
