I have an Audiovox SIR-PNP3 Radio Receiver that I have lost Signal on. It shows 3 Bars of signal but still searching. Anyhelp is greatlyu appreciated.

The cradle connects to the cigarette lighter connection for power. There is a connection for the Magnet mount antenna which sticks to the roof. The radio can output a radio frequency signal which you can tune your fm radio to receive. It has a number of frequencies to choose from so you can try to find one that is quiet and works best.

There was a car kit and a boom box that were made for the sir-pnp3. I do have both. It allows one to move the radio from the car to a home.
Search for the sir ck3 adapter. It is available on amazon. http://www.amazon.com/Audiovox-SIR-CK3-SIR-PNP3-Satellite-Receiver/dp/B0006FZYJ6

I heard these have a common problem with the antenna line breaking within the radio. I had it happen and replaced the radio. It's a shame since I'm sure I could have fixed it. I think it happens if the radio ends up hanging from the antenna lead. Any electronic tech or engineer should be able to check continuity from the antenna jack and find/fix it.

I use a wired fm modulator that the fm antenna passes through. When the sirius radio is on it blocks the regular fm signal preventing local signals from interferring. Do a search for wired fm modulator and you should find one. Mine actually fit inside the dash on my pickup.

I used a solution from another post on this site. Use heat gun to heat pc board after removing tuner assembly. Take care with the amount of heat used.

Looks like people are selling them on ebay for about $7.

This is a very old radio, and your antenna could be shot too. Try another antenna first.

The tuner is bad. The antenna miniport on your tuner has either a broken or cold solder joint and therefore will not receive. If it's under warranty, they will replace it, if not, you can buy the tuner re-built on Ebay for around 50.00 and is better than new. Hope this helps

i have the same damn problem its crazy
