Searching for 4.60 gcd for 65S I have found the fallowing information on some forums concerning this particular FW version of GPSMap 65S:

"4.60 was the final production release of the software. So yours was produced and loaded with it. Fundamentally it's a factory version of 4.50 there are just some copyright adjustments in the device label information. Devices that were produced before these models show 4.50 as latest. Picture 4.50 as basically just 4.50"

But 4.60 still not available for anywhere on the Net.

Any news/updates on this factory loaded, but unreleased version?
