converting non navi 2006 honda pilot ex

very useful post above....

anyways, the car will have the factory harness for power and speaker connections. this will plug directly into the navi head unit. you will need to run the gps antenna and wires for the factory xm, but it will be easy once you have the center consol open. The unique thing is, honda uses something called the Mbus adapter formerly used on alpine head units. If you connect your new navi head unit, you can connect the cd changer that came with the car, but you will need to do some serious wiring to get that running.

it would have been cheaper and better if you went aftermarket. purchase a nice metra dash kit to match trim if you have, get a nice flip out or double din indash navi unit and you the unit will ave aux, xm, sirius inputs so the combination is endless.

no real way of doing that since you want the xm to be controlled on the factory navi. You must pick navi or 6cd indash, unless you can head to a junk yard and look for any honda 02 and newer, and rip out the radio harness. that way you can power both head units on at one time and use which ever you like, but as i mentiond this is time consuming and a frankestein job.
