I have a 60cs, and it is a great unit! But..
1. the tracklog should not be limited by size. If I want to fill up the whole memory with just one log, I should be allowed too.
2.When storing an active log internally in the gps, it gets compressed! That means all timedata is lost! This is really stupid for pilots like me who uses logs to confirm flights (elevation,location,time).
Garmins code really should be open so groups with different needs could get their own configurations/features, like with linux: If it's not there, somebody somewhere is going to programme a solution.
