best nav/dvd in dash player?

[vip808]

Check out KenwoodUSA products. I have the Kenwood DDX-8017 and the sound quality, fit and features out shinned my Eclipse AVN5495. Unlike HummBob I've had to replace faulty Eclipse equipment and received very poor customer service from Eclipse Fujitsu-Ten.
The Eclipse AVN5495 is an all in one unit (DDX-8017 needs a separate hide away unit) If you plan to keep the stock speakers the Eclipse would better suit your installation.

You can absolutely install any double din unit in an H2 with the right kit and no modification whatsoever. The Eclipse units are very nice and I find they have the best nav solutions. However, the Z1 has a better screen and MUCH better Ipod, xm, and Sirius interfaces. Eclipse has released some ipod and sirius interfaces but they really blow!! Kenwood is also very nice but you will need to install at least one hideaway box with their systems. If you want pure nav and very good sound, go Eclipse. If you want decent nav, fairly good sound and very good interfaces, go Pioneer.
