The complex one could be something (like DC-DC converter) blown inside the unit. That is something a local mechanic can't figure out - better to head to the nearest Pio Service Center.
Or better still, go for a new HU, that was what I was thinking about.

So, may I assign the Hu to the bin?

In order of sound quality:
1. Kenwood KDC-U553BT,
2. JVC KD-R736BT or KD-R80BT/R90BT,
3. Pioneer MVH-X365BT or DEH-X4690BT,
4. Clarion CZ302A / CZ702A,
5. Sony MEX-BT3153U/4150U

These would cost 5-7K (street price). Check the links for features.

Default Re: Queries in 'Ask the gurus' section

Gurus, I am facing an annoying issue with my Blaupunkt system.

My 7-year old car had to undergo a rust job recently so I took it to a highly recommended FNG, where the entire dashboard had to be taken out to mend a part of the rusted firewall. While the rust job was done to perfection, the FNG mechanics seem to have done something to the audio system.

The issue is that the music system seems to lose power at various points in time. It has happened while I am driving, as well as when I start the car in the morning. One moment the music/system is on, the other moment it's gone! There is no set pattern to when my system decides to play (or not play).

I took it to Rhyme & Rhythm (another recommended place), where the guys weren't able to sort it out either. According to them, it doesn't seem to be a wiring / fuse issue. They said that some 'clip/connector' is missing and only the Hyundai A** guys will have it / be able to fix it.

The Hyundai guys are not interested to do anything because (a) it's not an OEM system, and (b) when I took the car to them, the system was working fine (Murphy's Law)! They tried to convince me there is no issue (and perhaps, by extension, that I hallucinate)!

Desperate for suggestions on:
- what could the cause be, so that I can explain the problem to the mechanics better, and,
- a good place (preferably in South Mumbai) which can solve my problem.

Thanks in advance!

It is definitely a loose connection at a connector, most likely the ACC connection:
1. ACC wire coming from the steering keylock
2. Harness connector in the dash (to where the HU adapter is connected)
3. HU rear connector

Have someone disconnect and reconnect the connectors.

Hi DerAlte;

As suggested by fellow members are you in particular I have gone ahead and fitted A kenwood M846 Amplifier in my spark.

So current setup looks like this

1) HU ---Pioneer DEH 4590 BT
2) Front Speakers: Kenwood 4 inch
3) Rear SpeakersL: JBL GTO 949 (Mounted on Rear tray)
4) Amp: Kenwood M846 (All 4 speakers are on Amp)

No Subwoofer

Now:
1) How to set amplifier: I am attaching photograph of various controls.
I understood that without sub I need to keep LPF and HPF switches to off. There are also 3 round controllers called LPF frequency and Input sensitivity A and B channel which is driving me crazy. Any help in this would be highly appreciated

Congratulations!!!

1. Yes, keep filters off. The Filter Frequency dial will not interfere if the Filter is off

2. Here is a simple tuning procedure (you might need a helper):
- Keep the A & B channel Sensitivity dials to full CCW (5V mark)
- Keep the volume in HU to about 1/3rd of full scale (e.g. 17 if 50 is max)
- Gradually turn the B channel dial CW (towards the 0.2V mark; I am assuming B channel is connected to the rear 6x9s) till the music is at a comfortable level in the rear seat
- Gradually turn the A channel dial CW till the music in the front seat is just slightly higher than in the rear seat. That is, other than the bass part, you should have to bend into the area behind the front seat to hear the rear speaker
- Check this proportion at different volume control settings above and below the 1/3rd mark

Thanks DerAlte! Will see if I can get someone to do what you've suggested.

Two questions here

1) After moving A & B channel Sensitivity dials to full CCW (5V mark) I was expecting zero volume from front and rear speakers but contrary to my assumption I was able to hear music from both. Was it expected?
2) There is some strange whistling noise coming from setup. I tried various combinations to reach to some conclusion and here they are

a) Its comes when I connect Channel A RCA cables
b) Channel B RCA cables have got no effect on sound
c) It seems to be increasing with speed of vehicle
d) Even when car is stationary engine off and ACC on whistling sound is present
f) It increases when playing FM and seems to decreases when using aux

Please help in getting rid of this sound since this is spoiling whole pleasure of new amplifier.

Thanks again

Yes, it is expected. The knob adjusts gain to suit the signal level of the HU, but even at the minimum point there is some internal gain.

The amp grounding is not proper. Ask the installer to redo the grounding. This is called 'ignition whine' - RF interference from the ignition system (hence the RPM dependency).

If everything else fails, wrap a couple of strands of bare copper wire around the RCA socket barrels at the rear of the HU, and then connect one end to one of the cover screws of the HU.

EDIT: It is also possible that the pair of RCA cables connected to channel A is not good (shield not good or open). Replace them and check.

Hi DerAlte!!

1) I have re grounded the amp taking care to remove paint from body using sandpaper to ensure proper grounding.
2) Wrapped few strands of bare copper wires on both RCA cables and grounded them to HU body.

Unfortunately whistling sound is still very much there. Secondly I noticed that on switching on headlight the sound increases and vice-verse.

Any other suggestion to get rid of this sound!!

Thanks in advance

I hope you have grounded the HU RCA sockets, and not the cables.

2 possibilities now:
1. Change the RCA cables from HU to amp

2. Is the amp power wire running near the RCA cables? Ensure that the wires are separated by half a car width for most of the run. For example, if you run the RCA cables down the middle of the car, run the power cable below the door sill, or vice-versa
