Loud static when turning on the car
 
I recently purchased a very well taken care of 2009 last month. Three times over the past few weeks I have had the startling pleasure of having my ears blasted with a very loud static when turning on the car. It happened twice in a row two days ago, once when the car was turned off set to AUX mode (ipod) and two hours later turned off on FM radio.

The awful noise is as if someone turned the radio station to a frequency full of static and cranked the volume all the way up to max volume.

I did a search on the forums and was not able to find out if anyone else has come across this issue!

I'm a computer geek...and understand the concept of how automotive stuff works but am clueless as to how to troubleshoot it! Any suggestions would be appreciated!

Thank you very much for your help, tips and tricks!

Is anyone going to help out Lauren?

The audio forum may be a better place for this, considering the wiring guru's are over there. Hope they can help.

I haven't heard of this problem as of yet.


TLDR: I am of no help.

Well the only thing I can equate to this in my 8 years of ownership is when my radio volume would randomly change. Turns out it just happens when something gets stuck on the volume knob.. so maybe try cleaning that.. who knows if something got stuck in there..

otherwise keep troubleshooting and hopefully someone can figure this out

I'd start by ripping out the head unit, checking connections, doing the old NES cartridge blow. (It's not that hard to do - look around for instructions).

Yikes.. This does not sound easy...let's assume that my radio is bad... Does anyone have any suggestions to aftermarket radios and kits (digital climate control) or where to find the factory radio for a reasonable price?

On the contrary, it takes about 5-10 minutes with a philips head screwdriver.

Skip to somewhere around step 8 or 9

Dunno how relevant this is but.... I've noticed that if my radio is set to AUX when ever I turn on my parking or headlights I get static from the radio if nothing is plugged into the AUX cord. Once I plug in my phone or ipod the static goes away.

Sounds fabulous! Thanks! I was on my break at work and was not able to find anything that made it look this simple! Guess I'll have a project to work on next week!

The only help I can add is to maybe turn the volume all the way down before turning off. i use my aux input all the time and if the wire is plugged in and i turn the car on- still in aux mode i hear what you seem to hear. i turn my volume down to avoid this. also i've noticed i'll get some static when i'm listening to music on my phone and its charging at the same time.

weird it happened turning it off when on fm- what happened after that? did the radio come back on? or is it only when u start the car?

Sounds like there is an issue with ground loop with external devices. The good news is you can get a ground loop isolator for $10 or so.

It ONLY happens when initially turning the car on. I have button mashed the crap out of every knob and the only way to make it stop is turning the car off and back on. Then it's fine... And does not give this awful noise or any static at all like others seem to have issues with.

I have been turning my radio off completely every time to see if the problem only happens when the radio is on when the car starts.

It is good pracise generally to switch off all accessories before switching off the ignition and is a cheap solution to your problem .

Update - When listening to my iPod via AUX input, I had the pleasure of having the static blast me while on the expressway. I had to pull over, turn the car off and back on for it to stop. I am going to refrain from using the AUX port at all for a week or to and hopefully the issue is what Compsurge suggested--ground loop isolator.

Random extremely loud static
 
I made a post about a month back (in the wrong sub-forum) about issues I've been having with the stock radio. Harmon Kardon speakers, automatic climate control.

It started off ONLY happening when turning the car on. Loud static would emit from every speaker and be so loud that your ears would ring afterwards. The only way to stop the noise was to turn the car off and back on.

It was happening weekly and thought I had narrowed it down to being the aux port, since my iPod was always plugged in. I spent the last two and a half weeks listening to nothing but the radio (painful) and had no issues with the static until I decided to listen to my iPod two days ago. I had no issues that day. The next day I had the radio back on and loud static came on while I was on the expressway.

I talked to a car audio installer and he suggested that my radio is most likely bad and that I would need to replace it to resolve the issue. Unfortunately I just don't want to spend the money to do so!!

In my previous post I received a suggestion to try an aux ground loop isolator and will be trying this to see if it resolves the issue. It has been ordered and is on the way, but I would like to know if anyone else has any suggestions or clues.

Thank you very much for your time and effort to help me resolve this issue! It's driving me nuts!

That is one way to see about fixing the problem for sure. The only thing is that I am thinking it might be 1 of 2 things. Either your Headunit or possible the Amp that is used with the Haromn system. I think it's under the passengers side seat. Unplug any wires running to it and start the car see if that would work.
