Anyone use SBM inout connectors on Navi?

[techboydino]

Has anyone successfully used the Rear inputs on the factory NAV unit? I found the correct connectors but want to know how it was converted to RCA type input. I can make the cable but of course in the US we rarely use this type for video so the impedence does not match.

How would you enable the display to show whatever video you are inputting?

As I recall you need to enter "test mode" first, then choose the aux input. Don't quote me - just read it on another site, don't have NAV so haven't tested myself.

You can enter that mode using a diag code with the hidden button, same type of deal as programming your destination while moving. I found some cables that are SMB female to BNC, then BNC to RCA. Im gonna give them a shot and see how it turns out.
