Hello,

I just purchased an 06 gx470. I was looking at the nav system and all the controls that are built into the system. I have only had it a few days and have not started mucking around yet, but I was wondering if there was a way to update the nav. I also wondered if there was a way to stream bluetooth or hands free phone calls through the system. I assume this would have to be done via an aftermarket update?
Any help would be great. Lots of good info on the forum btw.
