Kenwood KNA DV3200

12/10/2007 approx 3.30


I have a 2006 Bmw 3 series coupe. System - Kenwood Kvt 627, with KNA DV 3200 with KNA TM320 Live Traffic unit.

I have had a lead connected to pin 8 in the 26block connection behind my instrument Speedo, this lead is connected to the white pulse cable on the DV3200. Both the green parking sensor cables have been grounded via an earth as they are not connected to the parking system.


When I have plotted my destination, the system talks to me informing me that my guidance is about to commence after calculating my route and giving me 3 options shortest, fastest etc.


Unfortunately thereafter there is no more communication from the unit apart from the visual map route displayed showing me the road in which I am travelling. There are not voice guidance on when to take a left/right turn nor is there visual guidance on the map pointing out a turn lies ahead in as many metres etc.


When I have reached my destination the unit switches back on stating I have just reached my destination.


Can you please enlighten me what the problem may be and if possible have a solution to the problem which I am currently facing.


Please note, my GPS signals have picked up at least 5-6 satellites so that is working fine also, it is just the voice guidance and on screen visual prompts of when to turn that is not functioning.




The Traffic unit doesn?t always show in the navigation set up menu as being highlighted.

I have the very same unit, what you need to do is find the vehicle speed sensor and attach the white lead to it, then connect the handbrake lead too. You can`t fool this system, if it says connect to VSS, handbrake etc then connect them. You will find that once programmed you will get all the voice prompts and re-routing as it should do. Cheers, Cliff

IF there is no route guidance it is because the unit is not receiving VSS information from the vehicle.  Confirm that you are getting the VSS info from the correct source and or use Rostra Precision Control's cruise control guide to confirm your VSS wire.

Kenwood KVT-512 iphone compatibility

Just ignore the airplane mode prompt and if your wiring is correct everything should work.
With my BMW I had to connect both the solid blue (pwr ant) wire and the blue with white stripe (p conn) to the solid blue wire from the factory harness.

It isn't obvious that either of these are needed as the KVT-512 has it's own power supply but the way most factory power amps are installed the power from the KVT-512 is not used and the car manufacturers power amp needs to be turned on.

If you are listening to the radio the pwr ant wire will turn on the power amp, this didn't seem obvious because the BMW doesn't have a power antenna. And when you are using the DVD player or the iPod connection you need the P Conn wire to turn on the car power amp as the ant pwr is disabled because you are no longer using the radio and Kenwood assumes you will not need the antenna so no power to this lead.

Solder all three wires together and you should have sound all the time.

Does anyone knows where to conect the dimmer wire of a kenwood kvt-514 or kvt-512??

Connect to the side light live. So when you turn the lights on it dims the display.

Visit for latest firmware updates. Some of the updates are specific to map software (Garmin for KNA-G510) or bluetooth (Parrot for KCA-BT200) only.

Navigation not working

Recheck your connections on the kna-g510 and ensure it is getting power, not too familar with the kvt-819, but I've got the kvt -915 and when I pull up the screen, there is an icon right by the src icon, that looks like a wrench. Press that and find A/V interface and ensure that the navigation input is set to RGB, also you can back out and go to user interface and ensure the Navigation is set to auto intstead of manual. That may be the case if it is similar to the kvt -915.
