2007 EX-L After-market Stereo + Working Stock NAV

[thebasa]

Just ran into a problem at Car Toys on my 2007 EX-L. I'm replacing double din stock unit with an aftermarket and still wanting NAV up top to function but touch screen is disabled without factory stereo unit connected. So I found this post about doing jumpers for 2 lines that you can see are not addressed in the aftermarket harness (actually they said 3 lines weren't addressed). Car Toys tried everything they could to jumper those but failed to make the NAV work, so they eventually yanked the board out of the factory stereo and hid in under the dash, because the entire unit is too big to hide, having it send just the 3 that aren't addressed. Problem solved, however, this will all break down when the battery gets disconnected and I'll have to type the stereo code in again to get to the screen to unlock the NAV with the other code. Just wondering has anyone ran into this and accomplished the jumper solution on a 2007 EX-L and how I'd accomplish that. It would appear that the jumper pins mentioned in that post do not apply to the 2007. I'm not too experienced with testing continuity and other electronic stuff.

I'm a little confused as to what sources you are planning to use and outputs you are seeking or expecting.

Have you looked at one of these units to see if it would help? Upgrade any GPS Navigation Monitor/Display/Screen into Multi-Media System.
