Ford radio code for m050803?

And it's not 6190 or 6901 thank you

I've just seen the picture of your radio that you posted last week - the number showing on the display is NOT your serial number.
For a start, it doesn't begin with M or V.
To find the serial number of the radio, try pressing buttons 1+6 or 2+6 together, and you should see a number such as M123456 or V654321. If the number begins with M, post it on here and we can give you the code - if it begins with V, only a Ford dealer can help you.
(If the above method doesn't give you the serial number, you'll have to take the radio out to find it…)

Check for a decal in the glove compartment, or back page of the manual. That's where many mfgr's hide it. Hope that helps.

Stop messing about and take the radio out, you'll end up locking it if you enter the wrong code too many times and it'll be scrap.
