Anyone familiar with what is the latest on stereo? A friend's 2004 Cayenne S needs upgrade.

new head unit (Kenwood can adjust volume by **** so many easier for daily use)
Navi
BT
MP3
iphone
Rear view camera
Front and rear radar

Any shop in So Cal (SGV) familiar with Porsche?

Thanks.

 

Give Al & Ed's a call. Elie is the owner and they work on all high end vehicles including Porsche's. I'm sure there are plenty others out there, but I'm on the East Coast. Have spoke several times with Elie about whats possible on our vehicles and he is a very knowledgable guy. Carries anything/everything needed to install into our Cayennes.
