VW 02-UP ACCESSORY RETENTION HARNESS

The Metra Electronics XSVI-9003-NAV is a wiring interface designed to provide essential outputs for aftermarket radio installations. It supplies a 12-volt accessory power output with a 10-amp rating and retains the factory Retained Accessory Power (RAP) feature, which is often lost when the OEM radio is removed.

This interface also provides crucial navigation outputs, including reverse signal, parking brake signal, and vehicle speed sense (VSS). It is pre-wired for the ASWC-1 steering wheel control interface (sold separately), allowing retention of OEM steering wheel controls if the aftermarket radio is SWC capable. The XSVI-9003-NAV is intended for use in non-amplified systems or when replacing an existing amplified system.
