Think about how many hours you spend behind the wheel every week — your car’s dashboard is practically a second living room. Upgrading in-dash A/V gear can transform commutes, road trips, and errands into a safer, more entertaining experience. From crisp navigation on a 7" touchscreen to crystal-clear Bluetooth calls, modern receivers do a lot more than play radio. If you’re hunting for the best value, features, or a waterproof unit for powersports, knowing where to shop and what to buy makes a huge difference.
Shopping for car audio is a little like grocery shopping: you can go to a big box store for convenience, a specialty shop for expertise, or an online marketplace for broad selection. In the United States, popular places include Walmart for big value buys and sometimes third-party sellers, Amazon and eBay for variety and user reviews, Crutchfield for tech support and fit guidance, Best Buy for hands-on demo and installation through Geek Squad, and specialty auto retailers like Car Toys and AutoZone for vehicle-focused parts and service. You’ll also find replacement OEM units sold through suppliers like BuyAutoParts and aftermarket brands such as Navatlas and Digital Media available across several retailers.
Walmart carries everything from basic single-DIN Bluetooth receivers to double-DIN touchscreen units, and often hosts third-party sellers who offer OEM-style parts like a Toyota Highlander 2016–2018 OEM GPS/nav unit. It’s a convenient stop if you want a quick price check or a low-cost replacement. Remember to verify fitment and compatibility before you buy, since dashboards vary by make and model.
Crutchfield stands out if you want advice that won’t leave you guessing. Their vehicle selector tools, detailed installation instructions, and included vehicle-specific harnesses make them a favorite among DIYers who want a reliable fit. If you value step-by-step help and free tech support, Crutchfield is worth a look.
Best Buy blends showroom browsing with professional installation. You can audition head units in-store and schedule Geek Squad installation if you prefer a hands-off approach. This is handy when you want the peace of mind that comes with a professional install without hunting for a local shop.
Amazon and eBay are marketplaces where you’ll find almost any brand and model — from mainstream Pioneer and Alpine units to niche waterproof receivers for boats and ATVs. The review ecosystem helps identify reliable sellers and common fitment issues, but buyer beware: check seller ratings and return terms before committing.
AutoZone and Car Toys specialize in automotive parts and installations. Car Toys in particular focuses on car audio and accessories and often provides custom installations for high-end units. Local audio shops can be a goldmine when you want custom wiring, amplifier tuning, or a flush, professional finish that matches your vehicle’s interior.
In-dash systems come in several flavors, and picking the right type depends on your priorities: space, touchscreen size, smartphone integration, or water resistance for powersports. Let’s break down the major types so you can match gear to how you drive.
Single DIN head units are compact — about 2 inches tall — and suit older vehicles or simpler dashboards. Double DIN units are roughly 4 inches tall and typically include larger touchscreens, smartphone integration, and navigation features. If your dash has room for a double DIN unit, you’ll usually get a better interface and more features, like a 6.8" to 10" display, depending on the model.
These units focus on audio playback, Bluetooth streaming, hands-free calling, and multiple media inputs like USB and SD card. They’re the most common and affordable upgrade, and many offer built-in amplifiers with 4 x 50 watts of peak power for a noticeable audio boost over factory stereos.
If you drive a vehicle like a Toyota Highlander and need a direct-fit OEM-style GPS/navigation unit, aftermarket suppliers and resellers such as BuyAutoParts often list compatible replacement modules. OEM units can restore factory features like steering wheel control compatibility and integrated vehicle menus — a good option if you prefer factory look and function.
Waterproof receivers are designed for motorcycles, ATVs, boats, and other wet environments. Brands like Navatlas and Digital Media offer IP-rated marine head units with corrosion-resistant components and sealed connectors. If you ride in rain or plan to use the system on a boat, go for an IPX-rated model and marine-grade speakers.
Shopping is easier when you know which features matter. Prioritize the functions you’ll use daily — navigation, Apple CarPlay, Android Auto, Bluetooth, and camera inputs are top picks for most drivers. Here are a few specifics that will help you choose confidently.
Apple CarPlay and Android Auto mirror essential apps from your phone, offering navigation, music, messaging, and voice control. This makes most driving tasks safer and faster; think of it as projecting your phone’s interface onto a bigger, easier-to-read display in inches that range from roughly 6.8" to 10".
Screen size is measured diagonally in inches. A 6.8" to 7" display is common for double DIN units with good visibility; larger 9" to 10" screens offer tablet-like control but may require custom dash kits. Higher resolution improves clarity for maps and backup camera feeds.
Look for RMS power ratings (real-world output) rather than peak power, and for preamp outputs when you plan to add external amplifiers. Matching amplifier power and speaker impedance ensures clean, reliable sound — think of it like matching a shoe size: a close fit matters.
Backup camera inputs and parking sensor compatibility are essential if you want modern convenience in an older car. Many aftermarket receivers include a video input and wiring harnesses to make the connection straightforward.
Deciding between installing your new head unit yourself or going pro depends on your comfort level with vehicle wiring and dash disassembly. If you enjoy hands-on projects and have basic tools, DIY can save money. But a professional install gives a cleaner finish and avoids common headaches like loose wiring, buzzing, or dash rattle.
Before purchasing, measure the opening in your dash. Standard DIN width is about 7" across, while height depends on single or double DIN — roughly 2" for single, 4" for double. Some vehicles require a dash kit or trim bezel for a factory-like fit, so confirm compatibility with the retailer’s vehicle fit guide.
Common tools include a screwdriver set, panel removal tools, wire strippers, crimpers, and electrical tape. Parts you may need are a vehicle-specific wiring harness, dash kit, antenna adapter, and possibly an amplifier wiring kit if you’re adding power. Buy harnesses and kits from trusted suppliers to avoid brittle connectors and poor fit.
To simplify your search, here are five strong options across common needs. These picks reflect typical best-sellers and reliable designs you can find at major US retailers like Walmart, Crutchfield, Amazon, and specialty shops.
Pioneer, Alpine, and Kenwood consistently deliver feature-rich double DIN units with Apple CarPlay, Android Auto, and solid audio processing. They balance usability, sound quality, and reliability — great for daily drivers and road-trippers alike.
On a tighter budget, simple Digital Media or similar-brand receivers that handle Bluetooth streaming, AM/FM, and USB playback offer tremendous value. They’re perfect for drivers who want modern connectivity without breaking the bank, and you’ll find many of these at stores like Walmart and Amazon.
If you need a direct-replacement OEM GPS/navigation module for a specific vehicle like the Toyota Highlander (2016–2018), suppliers such as BuyAutoParts list compatible units. These restore factory functionality and maintain steering wheel control and integrated vehicle menus.
For ATVs, UTVs, or boats, choose a waterproof receiver from brands like Navatlas. These units withstand splashes and exposure, and often include sealed buttons and corrosion-resistant connectors — ideal if your driving includes wet or salty environments.
Sony and JVC produce intuitive touchscreens with strong smartphone integration and clean user interfaces. If a modern, smartphone-like experience is your priority, these brands deliver slick visuals and responsive controls for navigation and media playback.
Want to save? Shop around. Compare prices across Walmart, Amazon, Crutchfield, and specialist retailers. Look for bundles that include harnesses and dash kits — these can cut total cost and reduce installation time. Clearance windows around holidays often yield deep discounts, and some retailers offer price-matching or open-box deals for extra savings.
To keep your system sounding great, secure all wiring, use proper grommets where wires pass through metal, and avoid running power cables near speaker wires to reduce noise. Keep electronics out of direct sun when possible to minimize temperature extremes — remember, excessive heat in summer can accelerate wear. Update firmware when manufacturers release it, and match speaker and amplifier power to avoid distortion. Little maintenance today saves headaches tomorrow.
Upgrading your vehicle’s A/V system is one of the most impactful modifications you can make for comfort, safety, and enjoyment. Whether you choose a budget Bluetooth receiver, a double DIN touchscreen with Apple CarPlay, an OEM GPS replacement for a Toyota Highlander, or a waterproof powersports unit, there’s a solution at retailers like Walmart, Crutchfield, Best Buy, Amazon, AutoZone, and specialty shops. Measure your dash, pick the features you actually need, and decide whether you’ll DIY or go pro. With the right match, your car’s dash will feel like a tech upgrade that paid for itself in convenience and better drives.
