I mean I have downloaded it and ps4 says its also installed.

I have to home in to a radio freq. to start it

Question is : where on the map do i trigger this specific radio signal. ?

I went to red rocket & diamond city but did not get any radio signals other than what I already have.

so how to trigger and where ?

You have to be level 15 at least to get it

I am on level 98...so am I doing anything different or just be patient till it kicks in ?

It should automatically start, and you don't have to be anywhere in particular to hear the radio signal, I don't think. My character was at Sunshine Tidings when it was installed and I got the broadcast from there.

On the fallout 4 menu screen, under add-ons, does it say automatron?

I think you can do it anywhere on the map.

You just open up your pipboy and select the radio menu and the signal should be an available option that you can select, turn on, and listen to.

no its empty. but ps4 menu shows 'sold' and installed. waaaa ...whats going on

I see it now,,and its a good hour or 2 later. now this could have happened: the card went through and ps4 did its job but I assume they 'dont' activate the game as long as the card is not validated(europe card on a US server). I am assuming this all..but that cud be the only explanation why it took an hour or 2 to appear under the 'add ons' section. Thanks all ....and who knows , something for the records here

I'm glad it eventually worked for you. I figured that was your problem, but I would have no idea how to fix it.... I'm not on PS4...

Yes...the idea behind is (at least my experience), it will be not be evident immediately after the payment with a card. there will be a wait period , till the next batch process or so will start and then the payment will be handeled in the next wave. only then is the game activated from the server side, eventhough the client(ps4) mentions all is fine and dandy. my 2 cents , because I am still assuming this to be the case in absence of any other plausible theories.
