Strange issue
I just started using a car charger for my phone. I noticed that when I plug the phone in with the radio on, the radio gets very fuzzy and inaudible. It goes back to normal with the phone unplugged.
I have never heard of this, but somehow I am getting some kind of RFI interference from my phone only when its plugged in...
Anyone ever experience anything like this?

Is it a stock radio? Does it also do it on the CD? First thing I'd try is a different charger. Second, I'd try a second phone. If just your phone does it, sounds like you have an RF generation from the charging portion. Mine doesn't do that on a stock system.

Phone battery chargers are are notorious for casuing all kind of issues---strange ones too as you 're describing--- At most they should only be used as an emergency charge and best to use the home charger--Remember that GM hides the fuse to your car's ECM on the "cigarette ligher" circuit so the ECM's ODDII port is fused by the cigarette lighter fuse !!
Care needs to be taken on what you plug into the cig lighter--A deff no no leaving something pluggd in for a long time too

No issues here with the radio, while charging my AT&T or my wife's Verizon mobile phones.
We have often used both 12 volt power ports to charge both our phones together.

Most cell phone stores make the reccomendation to only use the car charger for emergencies-- mostly because they shorten the battery's life ----The batteries don't like hi and low spikes in voltages that come from the battery/alternator system in cars-voltages can drop to 11.5 when lots of accesories on and at start up raise as high as 14.50

DC chargers have an internal regulated power supply, same as home chargers, which maintains a constant 5 volt charge to the phone's battery, regardless of any input voltage fluctuations from the vehicle.

Myth or not --take my advice or not---just reflecting on what I've been taught and from my own experience--remember-cell phone stores make tons of $$$ from selling a $4 battery for $29.95 --I'm not tyring to sell anything

We use radios at work and some departments use them while on the charger. These batteries are toast within about a month.

I found out that this issue is not from my cell phone or charger. In this cold weather I finally had a need to run my rear window defrost. Same thing! When its on, static all over the radio, when its off, nice and clear! So theres some kind of issue in the wireing back in there. Whenever something else from the consol area uses power, the radio gets very, and I mean very staticy and inaudible.
Guess I need to pull out the factory system and take a look. What should I look for?
