so im getting my audio set up ready to install in my car. i read in a previous post how someone comment that the pxamg would work with the doms, i just want to make sure. i currently have the piex3 but text display from the ipod would be great.

im looking at picking up the PXAMG/PGHGM1 since mines a 05 with no nav traffic i dont believe i need the PXAMG/PGHGM2 harness right?
i want to have the ability to switch to a aux plug which the pxamg has.

my concern is would it interfare with the car?
this is what i have now on my table
doms nav to go
ipod composite cable for rca sound and yellow to video from doms
piex3 for aux only

now im planning on switching the piex3 to the pxamg since it has one AUX and ipod text.

would this work?
