Thanks to detroit202, I have installed my navigation system
in under 30 minutes. As I have written before, I installed and
uninstalled a Pioneer all-in-one unit, and partially tried a Kenwood
unit.

I finally decided on the Harman/Kardon Traffic Pro. Thanks to pnsji
I was able to buy the $1499 unit for only $379. (not a typo, it's
three hundred and seventy-nine dollars, or more than $1000 off)

I must say I love the unit very much. It is just as accurate as the
Lexus factory DVD navigation system on my other car, with the
except of not having an on-screen map. In fact, it re-calculates
missed turns faster than the Lexus system when I deliberately
make a wrong turn(or get out from the wrong freeway exit)

The install couldn't be simpler. The MB factory radio connector
plugs right into the back. All I had to do was to plug in the tiny
GPS antenna and stick it with velcro on the dash. In addition,
I tapped into the reverse light wire which is located next to the
gear-shift. I did hook up my cell phone's mute wire so the radio
will mute during phone calls. Not hard to do, since I had phone
mute wire hooked up to the original MB factory radio anyway.

Total install time from start to finish was 30 minutes!

After the install, I inserted the navigation CD. It comes with two,
East USA and West USA. I used East USA CD. GPS calibration and
road calibration took about 10 minutes and 2 miles of driving
around the neighborhood.

Entering destionation was simple with the rotary knob and the
predictive alphabet entry.

The navigation guidance voice can either be male or female,
Brisitish, American, German, French, and Spanish.

The best feature is the "factory-look" of the system. No flip-out
LCD screens. The "Mercedes-Benz" logo is also a plus.

I also bought a Becker/Porsche 6-CD changer and wiring harness.
It works great with the headunit. I plan to intall it in the glove
box this weekend. It fits, but I have to drill a couple of holes
in the rear of the glove box for the harness connector to go
through.

I'll write up a full review if anyone cares to hear about it. Let me
know. In the mean times, enjoy these pictures... Sorry about
the graffiti.. didn't want these people to end up on Ebay auctions.

Also, the picture quality is bad. It's 21 degrees outside and not
much warmer in my garage... Will take better pics of the GPS
antenna and the headunit later.
