I got my Perfect Pass system in the mail yesterday. Installing the Simple Cruise system on my 2005 Outback with the 310 Assault Carb Engine. I was surprised at how simple the install appears to be. Will see how it works out in reality... Also I thought I would mention that it appears to be same cost or slightly cheaper? to buy this system and then later upgrade to Stargazer. Basically it's plug and play to swap out the controller board and then add the multi-line display and GPS puck. I plan to take some pics of the install in case it's helpful to others thinking of installing a perfect pass system on a mechanically controlled engine.
