The sound seems to bouce around....one time i'll start the car and no sound...then I'll get back out and get in and start it with sound??! Whats going on?

is the sound issue on every source or just the ipod or something?

my unit froze one day and after I restarted my AV1 input randomly changed itself back to "None" so I wasnt getting any audio from my iPod. i had to go back and change the AV1 setting to IPod.

it doesnt sound like you are having the same problem but I thought it couldnt hurt to mention it just in case.

Here's a little test to eliminate 1 possibility... do you have audio when using the AM/FM radio and not when using any other audio source?

No audio anywhere...not even menu beeping... comes and goes.

Grrr!! Someone please help....I get sound..then no sound then sound. I even pulled it out to make sure no faulty connections or metal touching and would not work...put it back in and started the car and it works....plays for 10mins then out again?!?!?!

Take the car to someone that knows what they're doing, or give us more information.

Well pretty much when I start my car its hit or miss with the sound coming on. All is installed per direction...I have never had a problem before with installs. When the sound goes out I have to turn off the car and try to start again to see if it kicks back on.

Anyone??

Anyone??

Did you do the install yourself or have someone install it? I'd take it to a car audio shop and have them look at it, but the first thing you could do is test the harness with a volt meter.

Need more information

Do you have the speakers wired to an amp or are they wired into the HU? Have you put a voltmeter on the remote wire going to the amp (if you have one)?

I'm now having this problem. I haven't really had any problems with my unit since I bought it 2 months ago and now all of a sudden the sound cuts out once the unit warms up. After about 30 minutes of driving the sound goes out usually until I shut the car off and on. Whats the manufacturers warranty on these things anyway? It's an f90bt.

I am also having this problem. My iPod will come on - but no key beeps and I can't use sound via bluetooth.

The problem is when the system boots up you get no system sound. So no key beeps, no nav sounds, no bluetooth. AV output seems to still work. I have iPod and radio ok.

I'm thinking it might be to do with the BT upgrade. I think I'm going to downgrade the BT to 2.9 to see if I have the same problem

i had a no sound problem with a D3, turned out to be a aftermarket speaker wire grounding out on the car body, which caused the unit to disable the internal amp. If you have replaced speakers, check the connections and insulate them against the body to make sure

If the is something wrong on the speakers wires, or just one, the internal amp will shut off to protect itself.

Please post year, make and model of vehicle, what speakers are in there, and if there is a amplifier in the vehicle, wether it be stock or aftermarket.

2001 Lexus GS400 completely stock with stock amp. Worked fine for months than all of a sudden after about an hour of driving I hear a pop than no sound. Sometimes the sound comes back on by itself sometimes I have to shut the car off. Sometimes I can bang on the dash and the sound will come back on. I've pulled it out to see if theres loose wire but there isn't. Since there is no harness for a gs400 I used splice connectors because I didn't want to cut up the oem harnesses. The unit is mounted using the OEM mounts.

I downlgraded to BT 2.9 and it's still happening. If I don't use the unit for a few days when I turn it on I have no navigation or system sounds. Input/radio works ok.
