Ya i have the PAC as well and Its defiantly is the cause of the tuner issue. Happy to hear you got it sorted! Mine however is connected to ACC and the problem disappeared I guess you just need to be a little cautious about the batt drain....

I fixed my problem.... I had my swi module hooked up to the HU but I didn't plug in the harness as I am waiting for some OEM phone steering wheel controls to arrive. I thought I would hook it up and see and sure enough it all works as its supposed to. Ill just have to reprogram the pac swi when I install my phone buttons on my steering wheel. Hope this helps you with your problem!

Also.. Did your do this before you did any mods? (mines stock firmware) Is it bypassed?

Well this is kinda good news as it makes me think its something fixable... I sure dont want to have to take it out after all that work! Do you have a pac steering wheel control hooked up to it by any chance? Is it in a toyota? Maybe we can find some similarities in our setups which give us a hint....

Update - The update didnt fix it. Once I program the swi-pac Ill see if it still happens.....

I just bought and installed a avic-x710bt and everything went smooth except for 1 thing..... It seems that when am or fm is selected the volume knob starts the unit scanning through stations uncontrollably and the only way to stop it is to push the knob to the side. It does in fact turn the volume up/down as well but starts this scanning process at the same time even if the map is on and the fm/am is playing in the background. The volume knob works correctly in any other sources (ipod,cd). Should I reload the firmware from pioneer? I notice they have 3.0.2.1.0 on the site and my unit says 3.0
