1st, I would say I had a successful retrofit of the OEM navigation into my 2012 GT500 premium shaker, minus a few repining of speaker wires. It works, to a point, but I believe its my ACM that's giving me the problem...

1st problem, my door subs aren't working. They should work, fact the only thing that should work after the retro fit. It is not the amp or the subs. I put my original shaker unit back it, and they work, so leaning towards the NAV unit. Is the NAV unit's pin out (for subs) on a 2013 different from the 2012. I have a 2012 harness, but the nav came from a 2013. I don't know how to test the sub output from the unit. I put in an aftermarket amp for the other four speakers and all are good. I put a small amp right behind the climate control module behind the stock radio. Hidden out of site., didn't cut any wires, made a special harness from the old dash harness components.

2nd. problem....I cant adjust the clock. right now, I have no GPS because I am waiting on the splitter harness, so its disconnected right now. Is this the reason I cant adjust my clock?

I see this forum is a little slow now, probably due to facebook and other pages. If anyone can help, I really do appreciate it.

Awesome and I’d like to do this but not likely due to the limited amount I actually dricenit vs cost.

Have you been working with FORSCAN to do any of this? I’m working with it now trying to work with the TPMS functions. There’s very little for the 11-14 S197’s.

No, haven't used FORSCAN. Don't believe I can change any parameters with this. I may be wrong though.

It may have capability to do some things. I’ll have to compare my non nav as builts with some VIN’s I pulled that did.

How do I get the FORSCAN software and tool to connect to the OBD? Is there a subscription? I would like to try it. I read somewhere that (cant remember forum) a guy just changed a 0 to a 1 (I may have the wrong numbers, but you get the idea) and it changed his screen from the horse to the GT500 flash screen.

PistolWhip, thanks for the help.i ordered the OBD connector and downloaded the software. I went to the motocraft site and can't figure out how to download the as built data for my mustang. Any directions?

Forscan allows you to save a copy of the data that exists in all of your current modules. I took a USB drive and saved a copy of each module on that, in its own folder. I then save each mod that I confirm works, in a separate folder on that USB drive. Put it aside in my toolbox with F150 written on it so that I’ll be able to recover anything I need to right from that. I also saved the same files to a folder on my desktop for double redundancy.
