I finally got my Axxess ASWC module to work with all steering wheel buttons and my Pioneer HU. The problem wasnt with the pioneer, but with the Axxess's inability to grab control of all the steering wheel buttons. With some TLC and carful monitoring, I found on my car that auto-programming (volume + button) as instructed did not allow the Axxess to find one vehicle wires connected. I noticed this through monitoring the LED flashes after programming.
To get past this, I had to manually assign each button; one at a time. I did not have to use resistors or anything, just carefull reading of about 20 steps.
First, you must wire the Axxess ASWC per instructions for Nissan 370z. Here are the 370z's instructions:

Second, re-program all the wheel buttong manually following instructions starting on Page 8 where it says "*If the ASWC has been in a vehicle before"
through Page 10 of this pdf:
*Note - You need access to the unit's reset button to manually program.
