We recently helped a customer in Australia to procure the audio harness (Part No. 24036-AA000) for the R34 Skyline. This harness is to connect to the 5.8-inch widescreen LCD electric popup monitor. We also helped to source out the Xanavi Relay (Part No. 25230-AA000). While getting it brand new from Nissan Motor Co. Ltd, Japan is very possible, we assisted some cost savings by getting our hands on a used set.
Glad to help out. :)
