So you need to either get the ncs inpa software and cables off ebay or get someone to code it for you. The ibus adapter it seems will control the dsp but not keep it on. Coding the car to think it has a mid in place of navigation makes it not look for the nav head unit which is what is causing the amp to turn off.

Sorry if Im not super clear on some of these response. I have the flu and it sucks.
