I was wondering... is it possible to use my car's existing cell phone prewiring for an aftermarket cell phone? I know my car has the speakerphone speaker in it (and the mic, I believe). I really want a speakerphone for my cell phone, but cannot find one. I really think this is too complicated, and would be WAY TOO MUCH 'custom' work, but was wondering if anyone has in fact done it, or if anyone thinks it might be possible... Thanks.
(John Shellenberg, can I buy (where?) piezzo buzzers to put on the inside of my car and hook it to the existing alarm module? Thanks.)
