The recommend support unit ( that is purchased separate) to retain steering wheel radios functions did not work. ### ⭐⭐ Outrageous Price For Halfassery...But You Have No Choice But To Buy It! *by K***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on January 30, 2013* This unit was the only option, and a necessity for wiring in a new radio to my '08 HHR. Unfortunately, it's not well thought out, nor totally functional as-is.The good:*It DOES maintain On-Star.*It DOES allow the radio to interface with the factory harnesses.*It DOES maintain the warning chime for doors open/lights on/keys in igntion.The bad:*It DOES NOT maintain the signal blinker "click" without an EXTRA resistor - which must be purchased separately! Pardon me, but I expect EVERYTHING to work for the price of this thing!*It's FRIGGIN HUGE! If you have an HHR, and you are installing a factory-sized (Double-DIN) aftermarket radio, you MUST put the "Box" behind the radio pocket of the dash....there's not enough room to put it anywhere within the radio pocket of the dashboard.*Since it's so huge, and you must put it behind the console, there should be extra wire to allow for the length needed! The orientation of the wires, and their routing from harness-to box-to harness makes for a bird's nest of wires, but barely enough length to reach the radio.Long story short....if you have an HHR, this is a necessary evil. But be prepared, it's a nightmare.It ### ⭐⭐⭐⭐⭐ Great value *by J***B on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 2, 2022* Bought to install new head unit is son’s car was easy to hook up and works great to keep on star and bypass computer. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/2158163-metraaxxess-gmos-lan-03-lan-onstar-interface-for-non-amplified](https://www.desertcart.co.uk/products/2158163-metraaxxess-gmos-lan-03-lan-onstar-interface-for-non-amplified) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-13*
