Can Two Blaupunkt's Skip?

[Ogben Schmutzel]

Swapped the one that skipped on CD's for another and the new one skips!!!

 

Unit is fixed in the cage ok, but have not invested in the right adapter leads yet cos I may not keep it. However I am starting to wonder whether this could me or something because I know that Blaupunkt is quality kit and that two jumping is extremely unlikely.

 

Any thoughts???

when does it skip

regards steve

[Ogben Schmutzel]

Its random, smooth road, can happen anywhere, replay the track and it doesn't happen again. Rough road does not produce a skip, though I suppose it could!!

 

CD condition: tried it with nearly new, and some older, some have very minor scatches.

 

The CD's don't jump on anything else.

 

This is definately a different unit as the s/n is different.

 

On average it will jump once on a 10 or 15 minute run.

 

Edit: I should add that the jump is a 'few' seconds, not a whole track.

Can you take it out and bench test it at all? Does is skip if your standing still or only when moving?

 

If it is only when moving, did you use the right angle ariel bracket? Because of a bracket in the dash there is limited clearance at the rear of the unit. If it is touching this bracket it could be transmitting vibrations.

[Ogben Schmutzel]

MM, the aerial was a straight swap with the scala unit. I just used the existing bracket which is a right angle.

 

Is that what you were asking?

 

They have tested the one that I returned on the bench and it doesn't jump. I don't have the facility to bench test myself.

You say you dont have the correct leads, and that rough roads dont make it happen any more often. So its not skiping.

 

It might be losing power for a second or two (because of faulty leads), or getting a spike at certain revs or something. If your selling it, just re-sell the ISO on eBay afterwards. Id get the right leads first, before worrying about the unit.

[Masked Marauder]

I have to agree. I am wondering if perhaps it is the K-Bus wire, that is specific to VAG units. I would make sure there is no connections to any connector that does not need them.

[Ogben Schmutzel]

Ok, thanks - nuff said.

 

I read this earlier and have just got back from Halfords with a couple of bullet connectors and made the change myself. So far so good in that 1) it works, 2) it works without the ignition key in, 3) it remembers where it was on the CD.

 

So lets see what happens about the jumping!!!

 

Will post back.

oggy if the original iso is plugged into the radio with just the two wires swopped that is a problem because vw use the electric aerial feed of other manufactures as the timer wire so you are putting 12 volts perm into a 12v output/trigger wire :)

its the second red /white wire in :rolleyes:

[steve67car]

is pin 5 thick red/white if so is pin7 the same if so it aint antenna its a perm 12v feed in to radio not an out put :lol:

[Ogben Schmutzel]

Can't remember for sure but guessing, I'm pretty sure there are two thick wires and they are the earth (pin 8) and the perm live (pin 4) pretty sure pin 5 is not thick. Also the OE Scala radio has a schematic on it and that shows pin 5 as '+'.

 

I posted that schematic on the other 'jimping' thread.

 

This 'jumping' (or whatever it is) is entirely random, sometimes it doesn't do it for 20/30 minutes then several times in 5. Have to say though, that I reckon it is car specific rather than a radio fault so bit worried about buying anything else!!

The skipping. Does it go silent or just skip forwards or backwards or to the start of the next track. Give me something to go on!

[Ogben Schmutzel]

Hi MM,

 

Here goes.

 

Mostly the jump is quite small, say a second or two or less. The first time it happened I had to ask others in the car to be sure I had heard right.

 

Very occasionally it is more like several seconds i.e. there is a complete change in the phase of the music that is playing. Without looking at the display at the time that it happens I can't be sure, but I would say that the jump is then more like several seconds.

 

It never jumps a whole track, or to the beginng or end, at least not yet :lol:

 

It is random and unrepeatable. i.e. rewind slightly and jump does not happen.

 

Went berserk on 'Telegraph Road' on Sunday, but was fine on that track now.

 

Doesn't seem to be in a particular track position on CD.

 

This is always on manufactured CD's not copies or MP3. Haven't tried them yet!

 

I cannot spot a trend. i.e. its not early on in a journey - I wish it was then I could get people in the bl@*dy car and prove it :lol:

 

If anything it tends to be after 10 or 15 minutes travel but have sometimes gone twice that time without problem. I would say that it would happen at least once within 20 minutes or so,but not always. :lol:

 

On a couple of occasions I have heard a sort of buzz rather than a jump.

 

I reckon that it is related to car electrical system, but maybe this particular device is too sensitive?

 

Never noticed any strange buzz's on the old Scala unit.

 

Never had a problem with the same CD's in other devices. I'm sure it is not faulty or scatched CD's!!

 

It doesn't happen on rough ground, though I suppose it could.

 

Have changed Pins 4 and 7, but not does the aerial booster adapter yet.

 

If I think of anything else tht might help I will post.

 

I haven't got a clue ;)

 

Thanks for any input.

 

Cheers.

Well all I can suggest is to disconnect every wire except the speakers, positive power inputs and the ground connection. It could be one of the unused wires that are connected are causing the problem.

[MatTdi]

I reckon your in dire straits with this one...... :lol:

I started to compose a reply containing something about my 'investigations' and 'walk of life' but gave up!!!

 

Like I have with the radio.

 

A mate has lent me an old Panasonic that does all I want and has the VAG leads too. Just as well cos the Pana is not standard ISO like the Scala and Blaupunkt!

 

Anyway so far so good but I've been there before!!

 

See how it goes.

 

Incidentally the Blaupunkt jumped while staionary at traffic lights today.

 

Cheers.
