Conclusion: Having used a Kenwood DNX6960 in my 03 Harley Truck for over a year and being pleased with that Navi Unit, I decided to buy the DNX7190HD to integrate into my Gen1 CTS' 6-Speaker Bose Music System. I'm only using the units pre-outs as the signal source, as this method allowed me to keep the vehicles OEM Driver Information Center (DIC). Hence, I modified the stock radio and mounted the DNX 7190HD through the rear of the stock face plate... the unit looks factory.
Conclusion: Definitely a great product. Highly recommended for anyone. The EQ and sound adjustments you can make with this thing are among the best in the industry. A separate equalizer is not required, but with all of the features extensive tuning is required for optimal sound performance. The bluetooth audio function makes using either my LG Marquee or IV Gen iPod extremely easy. Call quality is great, and the response on the unit's touch screen is awesome.
Conclusion: this head unit is really easy to use, super fast, the bluetooth is awesome, it is unlike anything I've used for the ken wood double dins before. everything about it is really good about it, except for the random reboot from time to time. i called sonic electronix about it and it seems to be a hit or miss thing on this years ken wood. they are allowing me to return it in exchange for another since its within the 30 days.
