HELP: should i get new navigation unit? or this..
 

CAR -2007 HONDA CIVIC EX - with a replaced 2009 nav unit during the 3 year warranty.


1)
-Replace old (2009 OEM navigation with voice recognition unit), and get NEW NAVIGATION UNIT.

-get a converter so my steering wheel controls could control the new nav with voice rec/dvd/bluetooth/gps. etc?


=OR=

2)
-get and audio and video converter and hook it to the old navigation unit,

-and get a dvd/cd/bluetooth/ipod/cd player flowing through the converters to the old unit?

**This will have movie in motion feature**

What's a better option?
