DNX 5120 loses volume control

[Vital]

So a few times already out of nowhere my 5120 stops responding to the volume knob AND steering wheel volume control (swi-pac)Meaning whatever volume it was at the time it decided to not work anymore that's the volume it'll stay on even thou u turn that knob all the way both ways and screen responds to it. That volume indicator bars increase and decrease, but sound stays at the same level. Mute function (when u press volume knob) doesn't work either.

It happened twice already. Both were at most random times and circumstances, both got "fixed" by shutting the car off and turning it back on.

Any ideas?

Sounds like a bum connection internally somewhere. Is the unit still under warranty? Does everything else function besides the volume? It seems kinda strange that both the knob and steering wheel buttons don't work. AFAIK, the control the unit through completely different circuits. I guess there could be something wrong with the board, but then I would expect more things not to work. You got me...

Don't quote me on it but i believe everything else did work.

It's under warranty, thank god i got it from Crutchfield so everything should be fine in case i need to return it. I'd really like to keep it thou......

There's actually 2 more complains i have on DNX while we're at. Hope it'll somehow connect with volume issue so it could be resolved..

1. Most of my music is on 8GB usb flash drive. It is plugged in the wire coming out of the back of the unit. Every morning it takes from 2 to sometime 30!!! mins for the unit to "see" usb device. It keeps on telling me NO DEVICE FOUND even thou it's there. Pluggin it out and back in doesn't help much. Sometimes it also happens during the day (never while i'm driving, only when car is just started) but mostly mornings which leads me to believe that cold temperature has something to do with it.Meanwhile CD/DVD/Radio works fine.

2. Sound cuts off at high volume. I know the solution to this one - dnx is 4ohm and stock speakers that i still use are 2 ohms. I'm working on new sound system - speakers, amp, sub so that'll be resolved in near future.

Now could there be connection between all 3? (or 2 at least)

Thanx for your help btw

I used to have this issue with my old pioneer unit..it neded to be sent in to be fixed... IMO, rather than keep trying to find out what the problem is, I would just send it back and get a new unit.... no sense in wasting time trying to find the answer... it doesn't sound like an external onnection issue, more rather an internal one like Applebonker stated... and if that's the case, its not something you could fix... sound like a problem on the circuit board... again, we could speculate all day, but I'd definately say just save time and send it back

Just got off the phone with Crutchfield and they're saying they've never heard of these issues with DNXs so i'm getting a new one on Friday.

Thanx for feedback guys!
