2015 JBL Nav bypass

Has anyone figured out how to bypass the stock Nav unit? I have a 2015 with JBL entune audio plus with Nav. I looked all over the forums but couldn't find it. When I say bypass, I'm referring to being able to put in addresses and such while moving. Before anyone asks, I wont be doing it while driving, but it would be nice if the passenger could.

Thanks

 

Does it let you do so while sitting still at a stop light? IE without engaging the parking brake and/or putting it in park? I'm pretty sure that's how it was with my entune radio before I changed it.

If this is the case, there is a tachometer wire in one of the harnesses going into the back of the radio. You will likely need to sever this wire and possibly connect the plug-end of the wire to ground. It needs to be tested with a DMM and carefully analyzed before making any alterations to the wiring, though.
