Nav Add Ons, How Many Are There?

[linmk2]

I've just read with interest all the items that can be added to the fac. nav. system. I get the impression that the item such as the rear camera by Eclipse, just plugs in. Is that the case? Also, I was really impressed by the voice control system. Just how is that installed? Does anyone have a picture or link of all the inputs and outputs that are on the rear of the factory nav/radio system? Just what items can really be added? These items may have been covered in the past, but as a new member, I'm interested. While not trying to pry, what price range are these items and the installation cost? I understand that prices might be different in different parts of the country, but it would provide a guide. Wow , with this site, I'm learning something everyday. I hope soon I can offer help, rather than ask for it.

Mic Kit ~$50 (allows voice command)
Reverse Camera Kit ~$200


Not necessarily Nav only, but an auxiliary audio input ~$30-300

If you are even in the least bit mechanically inclined, you can do these installations yourself.
