Someone knows about headroom and car audio.
I like how integrated everything is with the stock Nav. Granted it is not audiophile grade, it does meet what I basically need. Getting the stock Nav system's guts upgraded to deliver a 4 volt signal and switched to pre outs is do able but at a premium. It'll take a dedicated tech and audiophile with access to quality components to get it done. Speakerworks out of Orange, Ca did quite a few of these in their heyday modifying Alpine 7909's (if my memory serves me right).
