Dudu7 radio error

Cool

Dudu7 radio error I installed my new Dudu7 8/128 radio yesterday and the radio doesn't work, it can't find any transmitters and only static noise comes out of it. I'm writing from Hungary and I'm using Google translator because I don't speak English. If anyone knows a solution, I would be very grateful.

Cool Csatlakoztattad az antennát a hátsó antennaaljzathoz? Ha igen, teszteld a következőket: 1. Hangold a rádiót egy helyi rádióállomás frekvenciájára. 2. Fogj egy darab drótot, és dugd be az antennaaljzatba úgy, hogy a vezeték hozzáérjen a középső érintkezőhöz. Ha bármit hallasz, az azt jelenti, hogy az autód antennarendszere sérült. Azt is mondd el, hogy milyen autó, milyen antenna, hogyan volt korábban csatlakoztatva, és mire.

Mikescotland The previous android radio works without any problems with the antenna, the car is a 2002 Toyota Rav4 Diesel, I will try the wired test tomorrow and write about the result.
Until then, thank you!

Mikescotland Hello! I tried your wired idea but there is no change, if I try it in the workshop then there is absolutely nothing but noise, if in the open air then there is strong static noise and barely audible radio transmission.

Cool vehicle > factory settings (password 108) > other settings > Antenna always ON
Check on and off with the radio

Cool

Mikescotland I checked and it's on. So far I've tried it in the workshop and there was no signal at all, but now it's coming in outdoors and here, but it's very bad.

Mikescotland

Cool possibly faulty unit then.

Cool

Mikescotland That's what I was afraid of too. Thank you for your help, I am infinitely grateful.

There used to be a setting where you could put amplification on the antenna signal when your antenna did not have a builtin amplifier (something like "antenna always on" Yes/No). This solved the low signal issues.
But I can't find it back.
@DUDU-Meng or @DUDU-HUANG : Has that setting be removed?

Cool

surfer63 Hello! This option has already been written and I tried it but nothing changed!

Cool

surfer63 A few posts ago, Mikescotland described where this setting can be found.

The signal is very poor. I think it may be a problem with the antenna or the radio's selected reception area.

dudu-lai Thanks for the tip, but the problem was solved: the antenna amplifier was not receiving power. I had to move the connector that came with the radio so that it would connect in the right place and it was solved. Thank you for your help.
