4H0035503AGRU Audi ROOFAERIAL

This part's job is pretty straightforward: it receives radio signals. That covers AM/FM radio, but a lot of newer vehicles also use the aerial for things like GPS navigation, satellite radio, and even the signals for your car’s security system or OnStar – type services. It’s basically the ear of your car’s entertainment and communication systems. Think of it as a receiver, picking up those weak signals traveling through the air. The signals come in, the aerial sends them down the wire to the radio or navigation unit, and that’s how you get your stations or directions. It's usually mounted on the roof because that gives it the best, clearest line of sight to the broadcasting towers. You’ll notice if this thing goes bad pretty quickly. Your radio reception will get really poor—lots of static, stations fading in and out, or not being able to pick up anything at all. If you use GPS or satellite radio, those might start cutting out too. It acts like a shield against interference, so without it, those signals get really messy. A bad aerial doesn’t always mean total silence, sometimes it just means weak, unreliable reception. You can find replacements pretty easily – we stock a lot of them at Fixparts Online, and they're not too difficult to swap out yourself, though sometimes the wiring can be a little finicky. Backed by trust: Roof Aerial (MPN 4H0035503AGRU) comes with a 12-month warranty!
