Retrosound motor 7 - tuner issue

[1950split]

Hi everyone,

I have installed a retrosound motor 7 radio as well as their DAB adapter and speaker.

The audio Bluetooth works as well as the microphone and speaker for calls.

When I switch to FM or DAB, the tuner seems not to work and I get a 00.00 FM display. What I noted is that the right hand side button does not seem to work.

When I turned on the radio the first time the tuner was searching radio stations but could not find them as my bus is parked in a underground garage.

Now I don’t manage to have the tuner seek anymore. Any help would be great as I really don’t know what is the issue.

I am using a Hirschmann red tip antenna with their DAB adapter. Red wire of the adapter is now connected to the blue power antenna lead. Has it on the ignition positive before.

Thanks,

Phil

So I did further testing.

The right center know works when not in fM and DAB.


I interverted them but this does not give a positive result.

I checked if my antenna is well plugged in and it is.

When I wait some time in fM or DAB I get a « no info » display.

Does anyone use a DAB adapter here and how did you connect it? I had first the positive wire on the ignition + of the radio and now on the antenna power lead as I finally found the wiring instructions. I don’t think I have fried the adapter having it first on the ignition + as its fuse is still ok.

Can you post the wiring diagram of the DAB or a link to it?

I found the culprit, one of my Motorola male connectors came loose.

I am not familiar at all as to how they should be fitted. Does the ultra thin center wire need soldering in the connector ? How do you do that?

Yes I have a retrosound radio but want to use my old Hirschmann Antenna. If I am not wrong, the double male connection cable uses Motorola connectors or are they of another type?

I must say that I don’t trust too much my soldering skills, and would rather go with a new cable even if not period correct. Does anyone have a source? I found a cable adapter on the net but it seems too short

[BarryL]

Oh, that Motorola is what you were referring to. Yes male Motorola to male Motorola it appears.

I bet you this guy could set you up if you didn't want to go generic. He has Red Tip antenna stuff: www.woodyscustomshop.com

He also has bus antennas. Caveat emptor applies here as this is not the "S" type. The mast is unscrewable: https://www.ebay.com/itm/AM-FM-Radio-Antenna-for-V...Sw0RlbwDee

That ^^^^style plug that screws onto the antenna is the one I use.

Thank you. I found a matching cable from Hirschmann .

Ok, so I am back again with my retrosound radio problem.

I changed the antenna cable and thought I could enjoy the radio but nope..

I managed to listen to the radio twice for a few minutes but when I switch it off I can’t switch it on again and use the tuner to find radio stations. It gets stuck on this FM 00.00 display and I can’t even switch off the radio.

I have called the reseller today and he is supposed to come back to me soon with a solution.

But in the meantime I am trying to figure out what is happening.

Could it be that a low battery could lead to these issues? I have attempted for pretty long time to have it work without the engine on. I have noted that scrolling through the menus is really slow and the radio gets stuck quite often.

Does anyone here using a retrosound have face this problem?

I am totally frustrated that it does not work after having spent lots of time and money for a supposedly nice radio

[BarryL]

How low is the battery?

Is your memory wire hooked to hot all the time?

Is the ground for sure?

Are the speakers all insulated from grounding?

I have a lesser Retrosound; works perfect.

Hi Barry,

I have the radio grounded to where my relais are too and the function perfectly. I have charged the battery to exclude the low battery voltage and it does not make a difference.

Wiring is done as per instructions.

So I am totally stuck.

There is an area setting in the menu for USA, EUR or Asia. Could be the issue

Hi,

Thanks for your reply. I have received a replacement unit and so far it is working.
