My daughter is considering replacing her CD30 MP3 in her 2011 Zafira B 1.7 Ecoflex Elite with a used Touch & Connect. However, she is not entirely sure whether this can be done as a direct replacement or whether she needs to use adapters etc, i.e. cage, ISO lead, aerial, other connection issues. Would be grateful if someone could explain step by step how this might be completed.

Any help, tips or tricks would be much appreciated.
