About a week or so after the upgrade, I lost control. The unit always thinks I am in motion. This unit was bypassed using the hardware method on initial install. Does anyone know if the 2.0 upgrade doesnt take the bypass well? I am just trying to figure it out. Pioneer tells me that the only way the unit gets motion is speed pulse and GPS. I have speed pulse hooked up. Could this unit be defective? Or is the hardware bypass and 2.0 not compatible?

Bypass works fine on mine. Do you have good GPS reception?

The speed on the screen is perfect, location is perfect.
