Which RCC A2 / NAC units are compatible with my C4 SpaceTourer (2019)?

[ymek007]

Hi all,

I have a 2019 Citroën C4 SpaceTourer, currently fitted with RCC A1
(firmware 0432A), no CarPlay/Android Auto hardware support.

I'm looking to upgrade to a unit with CarPlay/Android Auto and would
like DAB+ retained/added. I understand RCC A2 (Wave 2) adds CarPlay/AA
support without built-in navigation, and NAC adds full navigation on
top of that.

Could someone please help me identify:
1) The full list of RCC A2 part numbers (both DAB and non-DAB
variants) that are compatible with my VIN
2) Whether a NAC Wave 2 unit would also fit as a direct swap, and
which part numbers apply
3) Any known differences in connectors/wiring between RCC A1 and
RCC A2/NAC that I should be aware of before buying a used unit

My VIN: VF7**************[VIN obfuscated, can be read by forum staff]

Thanks in advance!

There are A1 and A2 units in both the RCC_EU_W2 (RCC Wave 2) and RCC_EU_W3/RCC_EU_W3_ECO (RCC Wave 3) systems. You have an RCC Wave 3 A1 (without Apple CarPlay/Google Android Auto and without DAB).

There are no direct swap, each unit must be coded to your car.
