There's a "RCC_EU_W3" ecuType, but all RCC Wave 3 that I found were "RCC_EU_W3_ECO". They both use the same firmware.
The "A1" or "A2" doesn't relate to Wave levels, but with hardware capabilities, specifically "Mirror Screen" support, PSA marketing name for the Apple CarPlay, Google Android Auto and MirrorLink - the A1 versions doesn't have that support. There are "RCC A1 Wave 2" and "RCC A2 Wave 2" variants and almost all RCC Wave 3 are A2 (but I did found some A1 variants). BTW I never came across a RCC Wave 1 and I think they don't really exist.
You can see the Wave level on the V850 Version ("Wx.x"), and the hardware capabilities on the (last) letter of the firmware version - for instance the "D" on the "049D" from one of the attached post images:
- "A": A1, without Mirror Screen and only AM/FM radio;
- "B": A1, without Mirror Screen but with DAB support;
- "C": A2, with Mirror Screen;
- "D": A2, with Mirror Screen and DAB support.
So for Mirror Screen support you need a A2 (last firmware letter a "C" or "D"), either a RCC Wave 2 or Wave 3.
It seems you had a RCC Wave 3 A1 and replaced that by a RCC Wave 2 A2 with a very old firmware (049). You cannot use your VIN to download the license key, you need to use directly the serial number of the new infotainment system.
