Whole idea of Metra is to use low level RCA output of the new head unit. You do not need CDM.
I did read that the OEM aerial connects to the CDM - if the CDM is removed can the aerial now connect to the head unit either directly or via the Metra Cabling too?
Factory antenna cable from the antenna connects under the storage compartment behind the passenger seat. Connect antenna cable from the new head unit to factory connection.

Many thanks for your input - I?ve now got a very good picture of how this will pan out.
