I just installed my new navi and it's all good to go. Only issue is my axxess isn't working properly. I've had this thing for years and never could get it to work right so I had a PAC installed with my Pioneer.
My new deck is a clarion so the PAC needed replaced, so with the new plug and play harness for the axxess I thought I'd give it another go. All I had to connect was accessory and ground. I did use the ground in the harness as opposed to a separate ground, but I like always prefer a common ground for everything. The directions do call for a chassis ground which I might have to try.
My taco is a 2011. The manufacture date on my axxess is 2010. I could update the firmware on the axxess, but the dang cable is $30, so I'd just buy a new one for that price. The new ones update by usb. That's assuming it's a firmware issue.
It runs the auto detect just fine, blinks 3 times confirming it sees my clarion and ends with a solid red light. But when I press my steering wheel controls, nothing happens. Looking for ideas on what to try next. Could be I've always had a bad unit as I've never been able to make it work.
Other than firmware and ground, there's not much else I can think of. Install was too simple and programming seemed to work, so I'm at a loss. FYI, head unit is clarion nx702.
