Review: Works well, pay attention to set up. - Used when replacing head unit in '06 VW Jetta. Proprietary German wiring requires adapters to fit after-market parts. Wiring colours matched perfectly to the new head unit. Pay particular attention to the instructions for initializing the adapter. I had some issues after installation as I didn't follow them correctly. This lead to the radio having no power the next morning. Disconnected battery for 30 secs and everything worked again, but it kept happening intermittently, and I have to keep going through radio set up menus. Contacted support and they were great. Here is their email: techsupport@metra-autosound.com Advice copied from the email they sent me: I would start the whole process over again by putting the factory radio back in, closing all entry points, and starting the car. Then turn the radio off, take the key out of the ignition fully, open and close the drivers door. Remove the radio, install the XSVI and aftermarket radio, turn the key to ignition for thirty seconds, take the key fully out, and open and close the drivers door. Start the car and reinspect, then advise back on the results. It also may be a good idea to check all connections, and harness' for them slipping slightly loose. It sounds like you just have a glitch in the vehicle. Advice followed (shouldn't have been so impatient!) and everything working well. Recommended. Review: Works pretty decent - Everything works my only criticism would be it doesn't actually restore factory function but it's close. With the original radio it was able to stay on with the key out as long as you didn't open the door. Once you opened the door the radio would shut off. This set up is slightly different but works great for what I need. It shuts off the radio after removing the key which works for me to avoid battery drain. Overall I'm very satisfied with this purchase. ## Features - Provides accessory (12 Volt 10 Amp) - Retains R. A. Tpu (retained accessory power) if equipped - Provides navigation outputs (reverse/parking Brake/vehicle speed sense) - Will work with the Monsoon/ system but not fender - The XSVI Interface series provides a 12V accessory power output that uses data control signals instead of conventional power signals ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002B5G4RA | | Best Sellers Rank | #5,950 in Car Audio & Video Wiring Harnesses | | Brand | Metra | | Brand Name | Metra | | Cable Type | vehicle wiring harness | | Customer Reviews | 4.5 out of 5 stars 247 Reviews | | Global Trade Identification Number | 00086429179862, 00086429198955 | | Included Components | Please check specs | | Item Dimensions | 2 x 3.25 x 8 inches | | Item Type Name | Metra XSVI-9003-NAV | | Item Weight | 8 ounces | | Item dimensions L x W x H | 2 x 3.25 x 8 inches | | Manufacturer | Axxess | | Material | Thermoplastic Polyurethane (TPU) | | Material Type | Thermoplastic Polyurethane (TPU) | | Model | XSVI9003NAV | | Number of Items | 1 | | Part Number | XSVI9003NAV | | Recommended Uses For Product | Vehicle | | UPC | 115971109482 086429179862 086429198955 777785919109 | | Warranty Description | 1-year Manufacturer's warranty | ## Product Details - **Brand:** Metra - **Item Weight:** 8 ounces - **Item dimensions L x W x H:** 2 x 3.25 x 8 inches - **Material:** Thermoplastic Polyurethane (TPU) - **Recommended Uses For Product:** Vehicle ## Images ![Metra XSVI-9003-NAV Non-Amplified Non-OnStar Harness to Retain Accessory Power - Image 1](https://m.media-amazon.com/images/I/61cfb3qEsGL.jpg) ## Available Options This product comes in different **Customer Package Type, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well, pay attention to set up. *by A***D on August 28, 2013* Used when replacing head unit in '06 VW Jetta.

I bought this because I dont always want to manually turn off the stereo every time I get out of the car. Installation was a little difficult at first but it's pretty straight forward once you see how the wires go. After installation, I was expecting the stereo to turn off when the ignition is off like the oem stereo but it stays on until you lock the vehicle. Not a big issue though. This harness is well worth its price for the job its supposed to do. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/8116309-metra-xsvi-9003-nav-non-amplified-non-onstar-harness-to](https://www.desertcart.tn/products/8116309-metra-xsvi-9003-nav-non-amplified-non-onstar-harness-to) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
