I have a 2009 base CE Toyota Sienna van and the stereo has always sounded awful...I have to have it cranked and I still can't hear it properly! I am wondering/hoping that a DPS system could make it worthwhile. I have asked my Toyota dealer about the Bongiovi system for this model but they seem not to really know much about it. Can anyone tell me if the Bongiovi DPS will work with this van and make the MUCH needed improvement???
