i read and looked around and saw that the blitzsafe is compatible with stock navigation.

but i read on a seller on ebay selling the USA Spec adapter for our car stating

"Will not work with vehicles with FACTORY INSTALLED external cd changer (or external factor cd player of Civic- will need to be disconnected), navigation, dvd system, satellite radio, or MP3 player."


does anyone know anything? or have this

also can anyone vouch for quality? retail is around $100 and i see it on eBay $65

 

It works fine for me. Acurabuddy has a post on this a couple threads down. The quality is very good, and you can control your ipod with the steering wheel controls. The one you are looking at on ebay (65$) i don't believe has the ipod integration it is a different model than what is suggested on this forum. I think it is just like the blitzsafe where it is only and aux input and no ipod connection. The correct model for our cars is USA Spec PA11-HON . It is also compatible if you have navigation as well.
