Re: Kenwood DNX9990HD
I was thinking about the 9989 last year, love the Garmin Nav, but I have an overland and few if any of the Kenwood interfaces for cameras and mics are compatible with the OEM stuff. I'd have to pretty much rip out or adapt everything. Nice for upgrading, however.
The big rub (and pretty much the only rub) on the 9989 model is that it was dog slow. I'd be curious to see if the 9990 is much more responsive. I'd like to see what one looks like in the WK2 dash. Although I'm getting used to the 730N, I just don't like the quirks.
Many WK2 are wired with two cables to the roof antennas, one for GPS/Sirius, the other fm/am. I don't think the kenwood is compatible with the GPS, however (needs a separate connection). Check with Crutchfield perhaps. I think the Kenwood was packed with a GPS antenna you could set under the dash.
This is what I was told last year about the 9989 model:
"This radio requires modification of the sub-dash structure of your Jeep. The height is just shy (about 7/32") of allowing the chassis of a larger double-DIN receiver to slide into the opening. So, you'll need to file the top or bottom of the cavity to allow for the receiver to get into the opening.
Next, the OEM GPS antenna, backup camera, console USB port, and OEM microphone use connections proprietary to the stock radio. So, we have no adapters to enable them to work with any aftermarket receiver we carry. I wish I had better news there.
When using the PAC C2R-CHY4 adapter you mentioned for the receiver installation, you can use this steering wheel interface with the Kenwood to retain the steering wheel controls"
