Hello... I have an older Allegro Remote. The closest I can match it to online is MBC 300PF N550 except mine does not have a slider switch (instead has separate AUX VCR and TV buttons on top row), mine has no inset (program button - Instead has a Menu Button), and lastly mine has four directional select ADJ buttons instead of just R & L.

I know how to put it into learning mode (Enter+0, then 99 Enter - End=Macro)
and I know how to Set Macro (Macro + ABC, End=Macro).

I am trying to find how to put this unit into the mode where it will cycle through all codes and FIND an unknown code.

I am hoping to get it to work for a built-in 12v LCD (brand name TRC) that is installed in a 2006 Limousine (Without remote!).

IF you know any instructions to put any older Allegro universal (it is a learning remote) into FIND mode, I'd love to try them.

Or, if you know where I could locate a replacement remote for the LCD ([Link: trc12volt.com]). As close as I can find so far it is TRC 7" and is either a universal or headrest model.

Failing that, any advice on the most universal remote possible?

Thank-you!
