$1400, I looked back 1 product revision before the 9990HD, and see the
Amazon.com: Kenwood DNX6990HD 6.1" Double Din Navigation/DVD Receiver with Bluetooth/HD Radio and Pandora Control for iPhone: Car Electronics
"6990HD" is nearly $600 less, and almost all of the same features are there......
cruthfield review:
Kenwood Excelon DNX6990HD Navigation receiver at Crutchfield.com
Seems like it has perfect rating, and nearly identical featuers to the 9990HD
