As I shop for a new head, I've found one gizmo that would really improve my life: a mute triggered by an incoming cell phone call.

http://www.pioneerelectronics.com/Pioneer/...1429,10,00.html

As I understand it, the unit detects the 800Mhz-900Mhz cellular phone's transmission in response to the tower's query and mutes the unit, pauses the cd.

For me, a pediatrician on call a lot, this would be GREAT. I often miss calls because I have the sound turned up loud.

Does anybody have any experience? Could I use it along with Pinky's mod? Does any other manufacturer have it too?

That would be fantastic! My only hope is if I see the light blinking...

Problem is that it won't work with SprintPCS. PCS uses 1900MHZ.

Analog uses 800MHZ, but how many people still use analog phones?!

 

We use 800 Mhz analog in Sheridan.

 

MY understanding, after talking with a stereo shop here in VA, is that your phone must be WIRED throughthe head unit. It doesn't "pick up the signal" through the air. And I don't want a hard wired connection.

I don't think so. I think it picks up the cell phone's transmitted signal and triggers the mute.

Designed for today's mobile phone user, the CD-CM1 connects to selected Pioneer headunits and offers hands-free mute and CD pause when cellular calls are sent or received. Compatible with Analog and most Digital phones (not compatible with 1900MHz-only phones). Adjustable 3-level sensitivity.

From the above link, which I just fixed.

When the phone is on, it is constantly sending a receiving. Switching from tower to tower, getting the time off the system and monitoring for when a call or message comes in. The only way that it could see if you were sending or receiving a call is if it had your phones programming, but in the digital world, it is encrypted.

Lance-

So you're saying that it would work for PCS or just normal digital?

Not so, at least for my analog AMP nAMP Vader 3620. I know there is rf emmission at the beginning and during a call that is not there other times. When I ride my bicycle, and my cell phone goes off, it produces interference in my am/fm radio that I carry adjacent to the phone.

I assume that the CD-CM1 senses this emission.

Your phone is transmitting at all times, but in a much lower power mode. A carrier can tell where you are at, at all times becuse your phone is regitered with at least one tower, more if you are in digital. The phone a tower are talking constantly. An analog phone operates at 600 mw and below, 200 mw and below for digital. The tower can tell the phone to increase or decease it's output power depending on how close you are to the tower. Some phones do put out some interference, some do not.

Digital is a sperate beast, as you have a pipe that all the phones share. In analog, each phone uses one channel. In digital, you can have 15 phones on just one channel. The tower and phone decide which channel you will be using, it doesn't matter if you are on analog or digital. It simply cannot monitor all of the frequencies at once. You can also receive text messages on digital phones, once the phone receives the message, it sends a confirmation back to the system. Would you want your stereo being muted then? What if the car next to you receives a call? According to FCC regulations, it would have to accept interference and you may not get the results you would want.
