Thank you for viewing. Mazda Eunos dedicated 12P and 8P audio installation kit, with wiring and connectors. I purchased this for use in an NB Roadster, but the used car I bought already has an aftermarket navigation system installed, so the connectors are not the standard shape and I cannot use this kit. Although it is unused, please understand that the box has been opened before considering a purchase. Please note that when shipping, I will remove the kit from the plastic case. Thank you for viewing.
