The parent company, GRAND NEW MATERIAL (SHENZHEN) CO., LTD., was founded in 2010 in Shenzhen, Guangdong, China. Its location provides access to the region’s electronics manufacturing and supply-chain infrastructure.[2] The firm initially focused on developing and manufacturing automotive electronic products, including car radios and multimedia systems, before expanding into connected-car products, CarPlay and Android Auto accessories, motorcycle navigation devices, and marine entertainment systems.[1]

The company reports having developed more than 300 OEM-customised products and serves customers across North America, South America, Europe, Asia, the Middle East, Africa, and Oceania.[2]

Employee and customer figures are derived from company profiles rather than independently audited statistics.[2]

Grandnavi products are broadly categorised into several segments.

Automotive multimedia

The brand manufactures aftermarket car multimedia systems, including 1-DIN and 2-DIN head units, Android multimedia players, MP5 players, and systems with smartphone connectivity designed to add or replace factory infotainment functionality.[1] Features vary by model but may include touchscreen displays, Bluetooth connectivity, FM/AM radio, USB and auxiliary inputs, GPS navigation, rear-camera support, wireless or wired CarPlay, Android Auto, Android-based multimedia functionality, and steering-wheel-control compatibility.[1]

CarPlay and Android Auto products

A significant category involves smartphone-to-vehicle connectivity. The company produces devices to support or upgrade Apple CarPlay and Android Auto, including wireless adapters, USB dongles, and AI Box-type products.[1] Some devices convert existing wired CarPlay connections to wireless, reflecting the aftermarket trend of upgrading older infotainment systems without replacing the factory head unit.[1]

Motorcycle navigation

Grandnavi offers a range of motorcycle-oriented navigation and multimedia displays. The catalogue includes 5-inch, 6.25-inch, 6.86-inch, and 7-inch-class displays featuring wireless CarPlay, Android Auto, GPS, Bluetooth, Wi-Fi, cameras, DVR functionality, and waterproofing.[1] Certain models incorporate quick-release or detachable mounting systems, allowing removal when the motorcycle is parked. For instance, the M782 is described as a 7-inch detachable motorcycle CarPlay/Android Auto display with an IP67 rating.[1]

Marine electronics

The portfolio also includes marine audio and entertainment equipment. Products comprise waterproof Bluetooth stereos and digital media receivers intended for boats, yachts, RVs, golf carts, ATVs, UTVs, and other outdoor vehicles.[1] Depending on the model, features may include FM/AM radio, Bluetooth, USB playback, AUX input, rear-camera support, and waterproof construction rated at IPX5 or IPX7.[1]

Beyond its consumer-facing brand, the parent company operates as an OEM/ODM manufacturer, producing goods under other companies’ brands or customising products for specific clients.[1] Customisation options include product branding, logos, packaging, languages, configurations, and bespoke designs. The company reports having developed over 300 OEM-customised products, positioning it as both a brand and a manufacturing business.[1]

GRAND NEW MATERIAL operates manufacturing facilities in Shenzhen. Company profiles describe an approximately 8,000-square-metre factory equipped with SMT production lines, automated insertion equipment, PCB testing equipment, aging-test facilities, and final assembly lines. The firm maintains an internal engineering team and quality-control system for product development and manufacturing.[1]

Grandnavi products are marketed with certifications such as CE, FCC, RoHS, and CCC, depending on the specific product and target market.[2] For example, one portable navigation product lists CE, RoHS, and FCC certification, while a motorcycle navigation product lists 3C, CE, and RoHS.[1] These certifications apply on a model-by-model basis rather than universally across all products.

The company describes its operations as international, reporting customers in North America, South America, Western and Eastern Europe, Eastern Asia, Southeast Asia, the Middle East, Africa, and Oceania.[2] Specific export destinations mentioned include South Korea, the Netherlands, Italy, the United States, Australia, and New Zealand.[2]

The name GRANDNAVI is registered as a trademark for automotive and navigation-related electronics. A US trademark filing under Grand New Materials (Shenzhen) Co., Ltd. covers goods including car navigation computers, car stereos, GPS navigation devices, vehicle navigation equipment, electronic displays, loudspeakers, and related electronics. The application was filed in April 2022, with a claimed first use in commerce in November 2021.[3]

Grandnavi functions primarily as an aftermarket vehicle-electronics and connectivity brand. Rather than focusing on a single category, it spans multiple related markets:

• Cars
• Motorcycles
• Boats
• RVs, ATVs, and UTVs
• Connected-car accessories

Common technological themes include vehicle connectivity, navigation, multimedia, smartphone integration, Bluetooth, CarPlay and Android Auto, waterproof electronics, and aftermarket upgrades. This positions the brand as a specialised automotive electronics manufacturer and aftermarket technology provider rather than a traditional automobile manufacturer or mainstream consumer-electronics company.

As of 2026, the publicly listed product range continues to include conventional car multimedia systems alongside newer connected-vehicle products such as wireless CarPlay/Android Auto adapters, AI Boxes, portable displays, and motorcycle navigation systems.[1] Marine and outdoor audio products remain part of the catalogue. Recent listings indicate an increasing emphasis on wireless smartphone connectivity, portable displays, motorcycle navigation, and waterproof multi-purpose vehicle electronics.[1]
