The Navigation is really Fast and accurate to within 3 meters of your destination, I have several other cars with built-in Navi but this one tells you the Street name instead of just saying right turn in 100 feet, the Clarion Powered Channel Sub is Perfect size to tuck in behind the passenger seat give good solid base. I will post the final photos once we finish modifying the panel. When we first installed the Kenwood DNX7100 we did not install any Amps yet only the powered sub and we connected it to the original door speakers with the factory bose amps on line and it sounded soooo sweet already I could not belive it, the we removed the factory bose speakers and put the JL Audio separates and bam it sounded soooo weak hench we had to install the AMPS, but if your not really into that loud loud sound the factory bose with this Kenwood and just a powered sub is more than enough.
