Query: PA15-TOY Review

This product has done exactly what it said it would do. I used YouTube to find some video of others who have installed this unit previously. That helped shorten my installation time. I also found at Checkers auto store,for $10, a pre-molded auxiliary headphone jack with RCA jacks to allow the unit to be used with a non-Apple device (without the 13 pin jack, but a headphone to headphone jack). Both hook ups have worked well since installation. Make sure you read the installation manual and flip the switch for the auxiliary headphone jack use prior to installing the unit behind the dashboard.
