I can’t emphasize enough the importance of reading the installation guide carefully before you attempt to use the Traffic Pro. It certainly would have saved us some time.

Harman/Kardon says that the Traffic Pro “is the most highly refined example of a sophisticated new breed of fully integrated navigation system.” I have to say that once you get over the installation and color display “issues,” the Traffic Pro is extremely well thought out and relatively easy to use. Don’t need a navigation system? That’s like saying you always know what road you’re on, always have the right map in your glove compartment, and have gas station attendants that are always willing to give you the “right” directions. We don’t need automatic transmissions, air conditioning, or even power windows for that matter. So why do we get them? They make driving more pleasurable and less stressful. A navigation system is no different.

To refer to the Traffic Pro as a navigation system would be an injustice. It is a highly refined radio, CD player, CD controller for a CD changer, traffic programmer, and last but not least, an excellent navigation system. So let’s get to the best of times part of the review: the functionality of this unit.

The basic layout of this unit is a standard DIN sized receiver with an extra large display in the center. Clockwise, there is a Left Control Knob (info/volume), ON/OFF Key, Tone Key, Traffic Program Key, select CD button, select Radio button, select Navigation button, CD eject button (which controls the detachable faceplate), right control knob (“OK”), ten (10) Multifunction buttons (directly below the display but a bit difficult to see at night).

In terms of general operation, turning the unit on and off is self-explanatory. There is one slight difference between the OEM BMW units. If the unit is still on and you switch the ignition off, it remains on for three (3) additional seconds unless you press the ON key, in which case the unit remains on for one (1) hour and then is turns off automatically.

By pressing the Tone Key you activate some of the basic adjustments associated with all radios such as the Bass, Treble, Fader, Balance, Filter (i.e., Flat Tone), Subwoofer, and Loudness settings. A nice feature not found on our factory head units is that the Bass, Treble, Fader, Balance and Loudness is each saved separately for all the different modes (FM, AM, Traffic Reports, Navigation Messages, Telephone, CD, and CD Changer).

The navigation system is relatively intuitive even if you’ve never used one before. Two (2) CDs cover the United States. Once you press the Navigation Key and confirm that you’ve read the warning not to program a destination while driving, you are greeted with four (4) options: i. Destination (used to program a new destination), ii. Destination Memory (previously stored destinations), iii. Points of Interest (P.O.I.), and iv. Last Destinations (up to fifty (50)). You scroll through the menu by turning the Right Control Knob and confirm by pressing “OK.” For a new destination, you first program the town and then the street (or centers in a town). If the same town exists in more than one state, you will be prompted to choose a state. When you’re entering an address, only the letters, digits, and symbols needed to complete a destination are displayed which can be selected and confirmed with the Right Control Knob or the corresponding Multifunction Key.

Once you enter a complete destination, the Route Menu allows you several options. You can either Start a Fast Route or Short Route calculation (last one used is displayed); Save Destination; input a specific House Number; an Intersection; or program Route Settings. The Route Setting menu allows you to choose between Fast Route, Short Route, or a Restrictions submenu of with/without Highway, Ferries, or Tolls. This is very nice indeed! The manual recommends “Short Route” for larger cities or metropolitan areas. When you’ve completed your destination and options, you can then confirm with the Right Control Knob at which time the Traffic Pro begins to calculate your route. A blinking “CD” light on the display indicates that the unit is still calculating the route. Once complete, the unit greets you in a male or female voice depending on what you choose in the User Option menu. I chose the sexy-voiced woman from the U.K. (English GB) over the “Americanized” (English US) voice option.

Low on gas? Hungry? Want to stop at a friend’s house or need to get to an airport? Just program a Stopover. Once you reach your Stopover, the Traffic Pro automatically guides you to your main destination. Stuck on the highway in a traffic jam? Just program in the length of the section to be avoided and the Traffic Pro calculates a detour route. Can’t tell you how many times that’s happened to me. Good job H/K! The navigation announcement has several different settings. You can have navigation only (current audio source is muted during announcement), a mix which allows adjustment +/- 6 dB, or independent volume levels for the audio and navigation.

Miss a turn or just don’t want to go the way the Traffic Pro is telling you? No worries… the system automatically calculates a new route. Know exactly where you want to start from but getting annoyed that the Traffic Pro insists you go its way? Just press the Left Control Knob and once the announcement begins, press it again and hold it till you see “speech announcement off.” Reactivate the sound by pressing the Left Control Knob again. There are so many other features/options that it would be unduly tedious to go through them all. Suffice it to say that you have other options such as displaying route settings, requesting current time, requesting current position, requesting a road list (allows you to scroll through the current road and road names up to the destination), and Points of Interest that are too numerous to name but I will name one. If food is one of your favorite points of interest and you are in an unfamiliar place looking for the nearest Italian restaurant, the Traffic Pro will list all nearby Italian restaurants and guide you to the smell of that mouthwatering marinara sauce!

There is one nice feature even when route guidance is not active. You can display the street you’re on and the number of satellites you’re tracking by pressing the Navigation Key and then the Left Control Knob. This is a very useful feature if you know the general area but can’t find a street sign or perhaps it’s too dark to see one.

The Radio Mode is activated with the Radio button. This displays FM, AM, Program Type (pty), Display (Dis), Regionalization (Reg), and Text (txt). The Traffic Pro is capable of receiving RBDS signals (Radio Broadcast Data System) which displays station broadcast information. Unfortunately this unit is not XM-capable which would have been a real nice feature. Perhaps some day?!?!

The FM band features four different display modes: DAS (Dynamic Autostore)
Seek Qual.; DAS Seek Name; Station RDS, and Stations Fix. Abbreviated names for receivable stations are displayed above the multifunction keys and are arranged in descending signal strength or alphabetically for FM “DAS Seek Qual.” and “DAS Seek Name” respectively. You can then choose the corresponding multifunction key to choose the station.

The Display button allows you change between program type (Pty on) or Frequency (Pty display off). This gives you the option to choose specific program types in FM DAS mode in which case only the stations with the particular Pty chosen can be selected. You also have the option to choose NO PTY and all stations will then be displayed. Examples of program types include Classical, Rock, News, Country and more.

Stations RDS mode displays and constantly switches to the best receivable frequency for the station. Station Fix is basically the equivalent to manual FM tuning. In both of these modes you can store up to 12 frequencies per waveband by holding down the multifunction key until you hear a confirming beep. The basic features for Scan and Search are all retained.

The Traffic Program (TP) feature is really quite interesting and presumably over time will be more popular with radio stations. If an RBDS station transmits traffic program announcements, you can have your current mode (CD, CD Changer, and AM) interrupted so that transmitted TP announcements can be played. You can also listen to one FM station while receiving TP announcements transmitted by another FM station.

There are two ways to select a TP Transmitter: automatic tracking or direct programming. Automatic always uses the current FM station as the TP transmitter. If the signal is too weak, the unit automatically searches for a new TP Transmitter. Direct programming allows you to choose a TP transmitter which is different from your current FM station. In all modes, you activate automatic tracking by pressing the TP button for more than two (2) seconds.

The Traffic Pro also features a telephone-muting option if a telephone system is installed in your car. The current program is muted and once you accept the call, the sound can be heard through you speaker system.

One final note about the radio: BMW factory units come with a diversity antenna which allows the OEM units to automatically switch between two antennas on the car depending on the signal strength. This feature works quite well but is not found on the Harman/Kardon Traffic Pro. In fact, nearly all aftermarket radios do not have diversity since it is a BMW specific option. So the fact that the Traffic Pro does not have this feature should not surprise anyone. I must say that I didn’t notice the signal quality was any different or inferior than my factory head unit. What is odd, however, is that the pre- production BMW Traffic Pro units which were used to solicit BMW NA didn’t have it either. This probably means that Harman/Kardon only intended to target the BMW Z3 crowd since that is the only car that I know of that does not have a factory diversity antenna built into the car. Odd to say the least! Even the new Z4 has diversity.

The CD (which is built into the unit) and the optional Becker 7860 6 disc CD Changer, which can be added as a trunk mount unit, have all the basic features found on most units. You can Scan Search, Fast Forward, Rewind, Random Play, Repeat a track, and display the number of tracks and total playing time for the CD being played. The CD Changer has several other options such as custom CD-naming and filtering although I doubt these would be highly sought-after features.

The unfortunate consequence for many BMW owners who decide to take the Traffic Pro plunge is that it is not compatible with the OEM BMW units such as Alpine. BMW uses a proprietary connection called I-Bus which, in all its wisdom, BMW NA decided not to license to Harman/Kardon USA. Of course the European BMW Traffic Pro’s are fully I-Bus compatible. In fact, they also have the diversity antenna option. Talk about second rate consumers!

There is also another benefit besides all the bells and whistles built into this unit, namely the sound performance. The TP has noticeably better sound quality over the BMW factory head unit (both the C33 and C43 models found in most E36’s). I don’t know how H/K did it but I can hear certain instruments on some CD’s that just were not there before. I guess the best way to describe the sound is that it’s more open and clear while still remaining transparent.

Still, with all its incompatibility, I have to say that the Harman/Kardon Traffic Pro is an outstanding sound/navigation system with so much more to offer than meets the eye. To put things in perspective, this unit, excluding navigation, is currently OEM on all Ferraris sold today. In the end, it’s a great alternative to the currently unattainable BMW-compatible Becker product. Good job, H/K! Here’s hoping that the already good fit, color and compatibility on the navigation system will one day be as perfect as the rest of the unit.
