Default Nav/Phone Hack in 2009 ES350
With some help from a kind Club Lexus member, I've made a hybrid disc that has V5.1 (1600) firmware with my 2009's ver.08.1 map data. Unfortunately, this has not worked. I was able to get it to work in my 2007 IS250, which gives me override and the latest maps. Has anyone tried and been succesful with "overriding" the '09 firmware for nav and phone?

My guess is that it will not work. Lexus redid the software so it wouldn't work in the 2008s and so it is probably a no in the 2009s too.
