Yes it is a Becker system.
Becker and infinity are the same company.
As for model no's I am not sure but I understand it is a Becker Silverstone 6 disc changer which will plug straight into the standard head unit.
I know this because I got a quote to have a changer added to the head unit and they got back to me the next day and told me it was made by Becker.
I have been quoted £260/$470 to have it supplied and fitted.
I have not had it fitted yet as I have been spending my money on other things.
I am keen to keep the stock head unit as it matches the dash.
