Sounds like a couple speakerwires could be crossed/shortcurciting somewhere...;)

Answer me this. I just had a new JVC KW-V840BT installed in my 06 dodge dually 3500 w/ infinity factory setup. They have even replaced the stereo once (all in a month) but my JVC refuses to play more then just a couple of minutes. All audio just stops, no matter what source. I am thinking that the JVC and infinity factory system are not shaking hands well at all. This was installed by the store and I have another appointment to just go upgrade to a totally different head unit completely.

ok , ive found the problem with mine. I checked the voltage between the earth wire on the head unit and the battery in the car. I found that when i turned the headunit up to around 17-20 there was up to 3volts differance, which is when it would cut out. So ive run a new earth wire and she's all sweet . Even the cd player works now.

i removed my car stereo and put a new one in, i didnt like the new one so i put the old one back in, but since i did this it wont store radio stations! why??? all the wireing is the same the fuses are all ok, so whats changed???

May not be an issue with the unit itself. Any blown speakers? Any shorted wires? It would be awesome to see if it worked in another vehicle or on a test bench. Then you would isolate either the vehicle or the radio as the problem.

The infinity system is unique in that the amplifier for each speaker is built right onto the speaker. You will need to bypass it by looking at the wire colors as they go into the JVC stereo, then finding them at the speaker. My suggestion is to just put 2 new speaker wires in and wire the speakers directly to the radio. You will have to routhe them through the dashboard but it's pretty simple to do. BTW, i know that vehicle well as I used to own one and customized the whole van.
