Pumpkin ND0279B

I've been on the radio since the purchase, early July this year, a noise, a rustle and crackle from the speakers. It is only heard when no sound comes from the speakers (it means Radio, Musicplayer, ... are turned off) and there is WLAN-traffic. Always when theres WLAN-traffic there is a rustle an crackle from all Speakers. The noise seems to have something to do with the WLAN.
The cause is not due to my vehicle, I have already tried the radio in several cars! And always when there is WLAN-Traffic there is the crackle and rustle! When WLAN is turned off, everthing is fine.

I think the unit has a technical defect!

Please help me, because so I can not continue to use the radio in my car, because the noise and crackling is very disturbing.

Thanks for support!

Hi,
i ordered two Pumpkin ND0279B.
One at the 10th July 2018 with the Ebay item number 302755111861 from pumpkin_coolstore.
Because I thought that the device is defective, i ordered a new Pumpkin ND0279B at the 12th September 2018 with the Ebay item number 273258843922 from Pumpkin18de.
Both units have the same problem. Only when WLAN is on. If I turn it off or of if turn on "mute", the whistle and crackle is away.
Your units are not properly electrically suppressed with a noise filter. I think that's the problem. I know I'm not the only one. And Pumpkin is not the only one which units have such noise, when WLAN is on. As seen here:

Maybe it's possible to fix it with an MCU Update. Actually a have installed the latest version KLD 2.88.

The error is not on the cars, where i've tested them. I also tested the units on my desk with MAGNAT Car Speakers. Also here the same!

It's really annoying. Especially when you navigate and you turn off all the music.

Thanks for further support!
