newest nav dvd for avic 90

is the cndv 40R the latest nav dvd for the avic 90, i have the avic 90 with the avh6400 and hate to part with it but the software is so outdated.im currently running the cndv20 that came with it and the dates on the main screen is 2002.i read somewhere that a 50 is coming soon ,but havent seen it .id try to goto the 40 but its $250 from pioneer and nowhere on ebay. anybody have some info on either a new 50 or 60 or a source for the 40 cheap.thanks

40r is the newest version, do not try and load the 60 disks or any other besides the 40r right now, doing so will lock you out of the system. There are 10 types of people in the world, ones that understand binary and ones that dont.

I can make you a copy for 50.00 of the 40R
