Dension woes

I know a few people have has these before and a few have installed them.

I bought the Dension Gateway pro for my car, first one was faulty, I got a second one everything's works but I have a few issues and I'm hoping someone can shed some light on it.

1. I'm getting that high frequency sound, like the dension is picking up interference from the alternator, this is only when connected to the iPod or the iphone through usb.

2. When I turn the volume down, it doesn't go right down on the front speakers, only does it on the dension, switch to CD player (the dash one as I removed the changer)

3. The sound quality is crap, poorer than radio and I would have all of my music in high quality.

I'm thinking of just sending back and buying an andrive.

Would @[GERMANIKS] or @[rebel.ranter] have any experience with these issues?

I Don't have any experience with these particular kits or how they are connected but the interference problem is usually a bad earth/ground, the other issues could be effected by this too.

It doesn't make sense that it would come and go when connecting and disconnecting the dension if it were an earth issue though.

What car is it please?

E39 with a retrofitted MID

Is the radio connected to the original radio loom?
I have seen a few cases where there was a Parrot or equivalent before using a SOT plug (These have much thinner wire gauge size than OEM usually), those plugs were left plugged in to the radio and it causes background noise issues.
If that's the case, remove it and go back to the original plug.
If not try the latest firmware.
If still no luck, I would say send it back
In my experience, Grom Audio is a much better and reliable solution for the E39/E46/E53...

Thanks Mike, I'm running the original loom.

That being said, now that you say that, one does get the adapter loom to integrate the dension to the existing system, that could be the cause of it.

No way of testing it really, might just send it back for now.

Maybe it's time I made that long overdue visit to you to get my sound deficiencies sorted once and for all.

Just had a look at the Grom Audio and it looks pretty decent, what I want is a Bluetooth car kit, facility for Bluetooth streaming, iPod/iphone.

Think I'm just gonna send the dension back.

I had faulty dension loom in the past alright.
Grom only has 3 wires and a plug for the cd changer. Original radio loom remains connected to the radio.

Is the grom situated in the boot then? How does it integrated, does it require cutting any wires?

Edit: just answered my own question, couldn't be situated in the boot, not unless one would run a very long mic cable [SMILING FACE WITH OPEN MOUTH AND SMILING EYES]

Only in the trunk when you have satnav, since the radio is in the trunk.
Bt dongle and mic wire are long enough to reach the front.

That makes sense, I'm gonna send the dension back and I'll be in touch, I appreciate the input from both you and mackers!

I have a DICE in my e39, and yes, I have experienced the engine noise through the iPod on occasion. Weird thing is that it's not all of the time. I keep meaning to relocate the connection to the back of the radio instead of running it all the way back to the boot to the CD Changer connections.
I reckon some sort of suppressor for the power supply would also help.

Mine is connected behind the dash as I had an iris unit originally.
My car doesn't have an amp so maybe I need to take this whole thing back to the drawing board. One of the major advantages of the andrive unit is that it's comparably powerful combated to the iris equipped cars.

Would a ferrite help eliminating some of the HF interference?

I was thinking about going down that route but I'm not sure where I'd put it, I'll take a picture of the loom later and show you what I mean.
