Check out this thread:Hello so I am trying upgrade my 4” screen to an 8” screen. Could an 8” screen from a 2017 mustang work with a 2019 mustang? And if so what would I need or is it plug and play?
What is HHP? Is that aftermarket? My assumption from the OP's post was that they were wanting to go to the OEM 8 inch. It's quite possible that aftermarket vendors sell full conversion kits with Android infotainment systems, that don't require the harness. But from what I understood, the APIM for Sync3 has a different connector on the back than the APIM for Sync1, so that's why you need the conversion harness. Basically, its going to bridge your car's Sync1 wiring into the Sync3 connector on the back of the APIM. Again, I'm sure aftermarket vendor's built this into their solutions, but for OEM to OEM upgrade, its a necessity.
I did not know that. But again, I'm not sure that that's the entire story. Again, most certainly, the Sync1 APIM connector on the back is different on the Sync3 APIM connector. So if you're car was a 2015-17 and 'non-premium' it came with an OEM wiring plug that would plug into the Sync1 BUT NOT the Sync3 APIM. Hence, the harness. So that leaves us only with 2 possibilities:What you might be forgetting about is that the 2018's and above already come with the USB hub that the sync3 apims need.
I didn't mean to offend by asking if you did it yourself. Just trying to hash out the nuances in my mind.Here's my sync1 from the back, still attached to the old 4" screen. Looks the same as the sync 3's 2019 and up on ebay, in any case. I believe either 2018 or 2019 and up, and a new sync3 apim will go right in. What I see as interesting is if you put one of these side by side, then aside from the extra USB connector (which I believe WAS depecated in the latest sync3 apims) you have to wonder what the physical difference is inside.. I heard more memory / flash on the sync3's but I don't yet have the guts to go find a few to tear them apart, let alone the $$$'s..
As far as the rest of your replies (if I did it myself, more to the story?, etc ).. look carefully at the background with the hp analyzer, soldering station, and associated "tron geek" hardware and ask me again if you need to, LOL. Been doing this stuff for hell.. 30+ years. Let me know if you want an old vintage amp rebuilt, a TV repaired, or whatever's cost effective nowadays... (wink)
Would I do it all over again? Maybe not...
