14' STX.stack style sync radio.I installed an aftermarket touch screen.with installed a touch screen pioneer with idatalink and maestro.I lost sync.what did I really lose? I still have steering wheel controls.Bluetooth is through the radio. So did I lose just voice control?

 

i was about to change my head unit to and i was wondering if there is a way to keep sync?

 

Certain models keep it.just so happens the one I picked doesn't.I think all the kenwoods do
