Request Fiat Scudo Radio Code (Clarion) PU-2294A

Anyone able to generate the code for this radio please? Van at work is boring as shit all day and music would be a god send!

I know there is a calculator available, but I don't know where it is for this one.

Codes needed to decode...

Serial - CL040161042255C
Bar Code - C70000005253

Edit-
Have tried a calculator and think it's 6421, but can't try it out as its on its last attempt and need to make sure. Can anyone else confirm?

Edit 2-
Nevermind. Bit the bullet. I can now decode Clarion codes (C7) for free too as well as Fords (M*****).
