I installed an aftermarket radio/tablet Linkswell Gen 4 and liked it but it had some intermittent issues not to mention the wife wasn't all that thrilled with it. I decided to take it out and put the Sync 3 back in and now the sync screen is not working. The AC controls, heated/cooled seats and climate controls work, but the screen is completely dead. Doesn't appear to come on at all. I did the soft reset with the power on/seek forward button to no avail. Also checked both the radio and sync fuses and even did a continuity test on both. Is there something I am missing here? Seems weird that uninstalling/re-installing would make it go bad. I am confident I got the cables hooked back up right as they are pretty much plug-n-play and don't think you can screw that up. I have an appt with the dealer, but was wondering if anyone here had any ideas?

 

I suggest disconnecting your battery for a few minutes, then hooking it back up, I'm thinking this may reset everything, and hopefully you'll get everything back.

 

Yep tried that too. Can't believe that in-intalling and re-installing would break something but maybe it did.
