I've read much of the discussion in this forum and decided to purchase the Kenwood DNX7140, an after market wiring harness, installation kit, antenna adaptor, ipod adaptor and license plate rear camera. After checking with a local shop here in Hawaii, I'm seriously thinking about doing my own installation. They want to charge me $95/hour and stated the install would take about 4 hrs (~$400+)!
Could I trouble you to assist me with any questions I may have or problems I may encounter with my installation?
I've already taken time to learn how to remove the smart factory radio 10 w/ premium sound system. I've studied and compared the smart factory wiring harness to the after market harness and the Kenwood harness connections. And, I studied the Kenwood Installation and Operation manuals.
Additionally, I've gathered the tools for the job e.g. crimping tool, ties, T25 torx wrench, electrical tape, and wire butt connectors.
I would greatly appreciate your assistance with connections that are not perfect or 100% compatible with the aftermarket wiring harness and installation instructions.
1) DNX 7140 connections without corresponding after market harness connect slots:
a – what location do you recommend to connect the wire for mute (brown)? Can I just tap into the chassis ground on the after market harness?
b – what location do you recommend in the smart to connect the parking sensor wire (light green)?
c – what location do you recommend to connect the wire the reverse sensor wire (purple/white)?
d – what do you recommend as far as connect the wires for power control (blue/white) and the power ant (blue) wires so that I retain function of the smart premium sound system subwoofer? Will I retain use with AM, FM, CD, DVD, etc if I combine these two wires with the 2 black wires on the smart wire harness?
2) DNX 7140 Accessory cable #3: For now I intend to keep the smart premium sound subwoofer. Do I need to connect the kenwood accessory cable #3 to the smart subwoofer and what wires do I need to connect?
3) DNX 7140 Accessory cable #2: What are relay 1 & relay 2 used for?
My name is natty and I see you're from NH (one of the states I've been dying to visit) :)
anyways, I've been trying to find more participants from the New England area to take my Smart Car owner survey. This is for a marketing strategy plan that I have to do for one of my classes at Fordham University. It'll only take a few minutes and my group and I would really love to hear from you. :)

I'd basically like to hook up the Nav and the iPod but I'm not familiar with the German antenna adapter. I'm considering the 8120 instead of the 5120. Does that significantly change the install? If we could correspond via email, that works too. I'd like to know how much you want for the adapter, etc.
I wish you were out here in San Diego. I'd love to grab a DNX5120 but the Smart Dealer here wants to charge me $2995 to install a ~$800 unit. It's been a while since I've installed a unit in a car. Do you think it's possible to do it myself or is it just too much work. I know I need the the dash adapter and unit but otherwise don't really know what I'm getting myself into. Any advice would be much appreciated.
Thanks for joining my mileage discussion. I'm very glad to hear you put on so many miles with ZERO problems. I still have a long wait, but maybe smart will start importing more cars and my date will get closer,sooner..
