I recently bought a 2013 Lexus GX460 it is in great condition with only 41,000 miles on it. The only issue I am having with it is that it does not sync well with my and my wife's iphones through the blue tooth. I have a 2014 Tundra DC SR5 and the audio system software is some much better. Is their way to upgrade the software of the 2013 Lexus touch screen and audio system to a newer version? I was wondering if anyone had ever done something like this without changing out the screen and audio unit? I appreciate any help you could give. Thank you
