I just updated to the newest firmware 6.0 and 2015 maps on my Z140BH. Everything seems fine so far. All the customization I've made (LED color, wallpaper, saved POIs, etc...) were retained through the update process as well. So thanks to everyone who helped get this update out!
Quick question though, are there any release notes for Firmware 6.0? I'm curious to know what exactly changed. I don't even see firmware 6.0 on pioneer's website.
