2001 Acura CL Type-S W/ Navi. What I want to do is add a cd/dvd/wma head unit in place of the stock cd/cassette player. Now..

1. Will there be any problems with the aftermarket head unit playing through the stock speakers?

2. Is the only GPS function that is lost during this process the voice of the lady giving directions?

3. Will I be able to play music through the new head unit yet also play movies though the navigation systems monitor? If so would it be possible to play movies on this monitor and have the sound play through the cars speakers with out any additional audio componants?

My overall plan is to buy this cd/dvd/wma head unit, a metra dash kit, an RGB converter and that is it, would I be set?

Sorry for all the questions and thanks in advance for the time and help!

 

Also...does anyone have any pictures of an aftermarket h/u (single din) with a navigation system in a 2nd gen CL?
