Over the weekend, I had Sirius satellite radio installed. The installation was expertly hidden from view (the receiver is in the glove box, and the antenna is hidden under the dash -- a small remote control is used to change channels).

As I drove the car home, I noticed the tire pressure monitor light was on. The owner's manual says that frequency interference may cause this light to come on. The tires are all inflated to the recommended PSI.

Is it possible that the satellite radio is interferring with the wireless system used for the tire pressure monitor?

 

Could well be the case BKH, I would suggest finding out from your Chrysler dealer and your Sirius radio supplier if the frequencies overlap.

 

I just bought a Satellite radio and will have it installed by a pro today. Are you still happy with where it's installed in your Crossfire? Did you ever get the frequency problem handled? I like the idea of completely hiding the whole system as it should be heard, not seen.

 

My Roady is in the glovebox and the antenna is centered at the base of the windshield. I have NEVER had any interference!!!!!!!!!!!
First thing I would do is check the tire pressure. It's getting colder and I have had to adjust mine twice. Sometimes the light will be on first thing in the morning, but after a few miles (tires warm up and pressure increases) the light goes out and never comes back on.

 

I don't think the radio will cause the light to come on. It only receives not transmitting. But just turn off the radio and see if the TP monitor light goes out.

 

After talking to the installer at Circuit City, I swapped the mobile unit for an in-dash Alpine AM/FM/CD/SIRIUS unit. The antenna is mounted on the dashboard and so far it's been just fine. The Alpine is far superior to the Infiniti as a receiver and all I given up is the ability to take the satellite radio indoors. But I figure if I really like it that much I'll just get one for indoors. The antenna isn't that obtrusive looking on the dash and I've had no problem with frequency interference.
