I have a few Questions

[Statella43]

Thanks to the help of Suns Fan I just installed a OEM touch screen navigation unit. Now that I know it works I'm interested in installing a back up camera, since we all know about the poor back up visibility that came with our H3. Does anyone know how to integrate one with a factory unit besides a Pac adapter b/c they are soo damn expensive. My next question is I saw a post a long time ago about installing shock sensors to a factory alarm. I was wondering if anyone has info/part numbers/diagrams on how to install either of these two things?
