What is "Set TP Volume" on PCM?

TooSixy · 10-09-2009, 12:56 AM

When you press the SOUND button, followed by OPTION, there is an option labeled "SET TP" at the top right corner, and the description says "Set TP Volume".

What is this? The only reference I found in the manual is "Speed-sensitive Volume". Are they the same thing?

TIA.

traffic program, i asked the same..

can we set the speed sensitive? if so how?

traffic program i think works in europe, i think we might have it in major cities tho?

TA Volume or TP Volume? I believe TA volume sets the volume the "Traffic Advisories" come on at. Speed sensitive volume is the GAL setting, but it is only present in the basic system, it does not exist in the Sound Package Systems or Bose systems. From what I can tell, you can not adjust the speed sentitive volume settings with either of the two "upgraded" sound systems. It is a bit of a shame, because I find my Bose system doesn't adjust the volume load enough at speed with the top down.

mine adjusts it a lot right at first.. like 0-30 is louder for sure.. and 30-0 is quieter for sure.. but 30+ it seems the same.

The Bose system choses to use a system called AudioPilot ( a DSP feature built into the Bose amplifier)...rather than a speed (via a CAN bus RPM message or direct RPM hardware input) signal.
A microphone in the car listens to ambient cabin noise and adjusts the amplifier output accordingly...most people just turn it off.

I have found that if you have TP checked, my radio will sometimes change the station upon restarting the car. If I am listening to AM and shut the car off then restart later, it will often change to FM.

TP can introduce radio changes and interference if left on. It was the source of complaints regarding PCM 2 problems until discovered what it caused. In the Boston area it causes radio station changes and odd interruptions unless turned off.

Thanks for the info.

Interesting observation - I'll have to try it with it off. BTW, it is supposed to change stations to pick up alerts, so I think it is working correctly - problem is very little alert info being actually broadcast.

AudioPilot is useless. "StevePilot" with thumb on the MF wheel dial is what I have to use.

AP is either broken, Bose is FOS, or both.

TP (traffic programme) was non functional in the US..It works fine in europe. What you are picking up other signals from some FM stations. In Boston it kept switching to some Regge station...fine if you like Regge. This was on my 06...Haven't used it on my 09!

Thanks for the clarification and info, guys. Much appreciated.

Traffic Program (TP) is the radio feature that uses the RDS (RDBS in the US) system which uses FM radio side-band frequency space to identify official traffic update broadcasts. The way the system works is if TP is enabled, then whenever there is an official traffic announcement on a radio station, that radio station would send out a TP marker signal before the traffic announcement, and one at the end of the announcement. The car's audio system would the switch sources automatically so you would hear the traffic announcement and then switch back at the end of the announcement... the driver would need to do nothing.

This works great in Europe, where traffic announcements are of high quality (ie meaningful and usable by drivers) and where alternate routing schemes exist that drivers can actually use to get around issues.

This system, while available in the US, is not supported hardly at all, because of a host of reasons, I would imagine:

Commercial US radio relies on you listening to the commercials around the traffic annoucement in anticipation... so autoswitching would effectively cut out the commercials... and reduce comercial time value near traffic annoucements
Most US highways do not have usefull alternate routing possibilities except what local townies might know about, if they even exist.
The traffic annoucements are usually useless to drivers, as identifying where the incident is relative to where you are, is impossible for a driver to do - incidents are not reported by mile markers on highways frequently but relative to surface streets which is practically useless to drivers without a map and time to study it... not good while driving.
Traffic annoucements in the US tend to come on AM stations, while RDBS is for FM broadcasts.

So unless you are in the US and know you have a local RDBS station that gives you useful data.. .just turn TP off in the US.

Outside of the US and most of western Europe (where the announcements are, of course, in the local language), I cannot say how useful it is.

To compensate, at least the 997.2's have the navigation with xm navtraffic service option... however, it will only reroute you IF you have an active route going. It doesn't see that you are driving along I-55 heading north and suggest alternate routes as you approach an incident, in order to continue going north on I-55. You have to look at the traffic incident messages that show up on the map, click them manually and figure out what to do before you get caught up in a traffic jam. Not ideal.

If we could store customized route requests for drives, that would be great (since we sometimes need to reject streets that don't exist in reality, or want to force a specific route because I know something about the best way to go that the nav system doesn't).. but it isn't possible currently afaik.

More than you wanted to know, I'm sure.
