Merge Screens policies referenced from their Refund & Warranty Policy and Shipping Policy, accurate as of Feb 2026.

1. Customs, Import Fees & Shipping

The price you see is not always the price you pay. Many aftermarket screens ship internationally, and carriers can charge customs or import duties at your door.

Merge Screens: Ships within the United States only. Their shipping policy notes that some orders may include a tariff of under $50, paid by the buyer. Their refund policy (Section 2.6) adds that out-of-stock items may ship from an overseas warehouse.

Two shipping options: free standard (8-12 business days) or premium (6 business days). Processing starts 1-3 business days after they get your vehicle photos.

Reference: Merge Screens Shipping Policy, "Tariffs" and "Shipping Options" sections; Refund Policy, Section 2.6. Accurate as of Feb 2026.

Car Tech Studio: Ships worldwide. Free on every order. We cover 100% of customs and tariff fees. No cap. If a carrier charges you anything at delivery, send us the receipt and we refund it.

Processing takes 1-3 business days. Delivery takes 6-8 business days via DHL, FedEx, UPS, or USPS.

Outside the US? This is a big deal. Car Tech Studio is one of the few brands in this space that ships to Canada, the UK, Europe, and beyond with zero customs cost to you.

2. Returns & Restocking Fees

What happens if you need to return a unit?

Merge Screens

Returns are accepted within 60 days from the order date. Restocking fees depend on the product type:

Product type	Restocking fee
Tesla-style screens	20%
CarPlay modules	20%
Accessories	30%

Additional details:

• If you received a replacement unit and later return it for change-of-mind reasons, a 50% fee applies (Section 1.6).
• Cancellations must be requested within 2 business days of the order. A 3.5% payment processing fee is deducted (Section 1.1).
• Sale items (including Black Friday, holiday discounts, etc.) are non-refundable (Section 3.1).
• Refunds are processed 21 business days after the returned item is received, plus 3-10 business days for bank processing.

Reference: Merge Screens Refund Policy, Sections 1.1, 1.2, 1.6, and 3.1. Accurate as of Feb 2026.

Car Tech Studio

• Compatibility issues: Work with our support team to troubleshoot. If we cannot make it work after trying, we issue a full refund and cover return shipping. No restocking fee.
• Change of mind: Up to 15% total (5% payment processing fee + 10% restocking fee).
• Cancellations: No fee if cancelled within 7 days and before processing. After that, a 10% cancellation fee applies.
• Sale items: Returns accepted.

Refunds are processed within 3-10 business days.

3. Pre-Ship Compatibility Check & Guarantee

Nobody wants to rip apart their dashboard and discover the unit does not work.

Both brands try to prevent this. Both ask for vehicle photos before they ship.

Merge Screens requests photos of your head unit, dashboard, and main interface. Their team checks compatibility and configures the unit for your car before sending it.

Reference: Merge Screens Refund Policy, Section 2.0 and "Unverified Orders." Accurate as of Feb 2026.

Car Tech Studio requests a dashboard photo too. We use it to verify your exact trim level (factory nav vs. base audio, Bose vs. standard, etc.) and make sure the harness we send is the right one.

So both brands check compatibility before shipping. The difference is what happens if something still goes wrong.

Both require you to work with their support team to troubleshoot. That part is the same.

At Car Tech Studio, if we cannot fix it after trying, you get a full refund and we cover return shipping. No restocking fee. That is our compatibility guarantee: your steering wheel controls, backup camera, and factory features keep working, or you get your money back.

4. Hardware: Knowing What You Are Getting

When you buy a phone, you check the processor. Your car screen deserves the same scrutiny.

In this market, hardware specs vary a lot. Two screens that look identical on the outside can run completely different chips inside.

Car Tech Studio keeps it simple. Every premium head unit ships with a Qualcomm Snapdragon 6125 8-Core processor. No guessing. Consistent performance for Wireless CarPlay and Android Auto.

This applies to our premium head units specifically. Tesla-style screens and modules use different hardware.

5. Warranty & Ongoing Support

Merge Screens offers a 1-year warranty on all products. You can buy an extended warranty within 30 days of your order. Products that arrive faulty get a 60-day free replacement (assessed by Merge Screens).

Support is through WhatsApp only. Weekdays, 10AM-4PM Eastern.

Reference: Merge Screens Refund Policy, Sections 1.7 and 2.5.1-2.5.2. Accurate as of Feb 2026.

Car Tech Studio offers:

• 2-year warranty on premium head units. 1-year warranty on modules and Tesla-style screens.
• Lifetime technical support. Not 30 days. Not 90 days. For as long as you own the unit. Question during install? Problem two years later? Reach out. You will get a real person, not a chatbot. Available across multiple channels including email and WhatsApp.

6. Pricing

We are not doing a product-by-product price comparison. The catalogs do not fully overlap, and each brand sells products the other does not.

But there is one clear price gap worth noting. Modules: Car Tech Studio averages around $450. Merge Screens averages around $599. Tesla-style screens: similar pricing between the two.

Beyond sticker price, think about total cost of ownership:

• Car Tech Studio covers customs fees. Merge Screens may not.
• Restocking fees: 15% vs. 20%.
• Refund speed: days vs. weeks.
• Compatibility guarantee: full refund if Car Tech Studio cannot fix it after trying.
• Lifetime technical support: something goes wrong a year from now? You still have a team to call.

When you are spending $500 or more, these differences add up.

Frequently Asked Questions

What is the difference between a "Tesla-Style Screen" and a "Head Unit"?

"Head Unit" is the technical term for your car's stereo and screen. A "Tesla-Style" screen is a specific type of head unit that is vertical and large (usually 10-14 inches). Car Tech Studio sells both vertical Tesla-style screens and standard horizontal head units.

Is it safe to buy from outside the USA?

Yes. Car Tech Studio covers customs and import duties worldwide, so international buyers do not face surprise tax bills at delivery. Merge Screens currently ships within the United States only.

Can I install this myself?

Yes. Most of our customers do it themselves. Both brands check compatibility before shipping, and the unit connects to your factory wiring with the included harness. If you would rather have a pro handle it, find an installer near you at caraudioshops.com.

What if the unit is not compatible with my car?

Both brands check compatibility before shipping using dashboard photos. At Car Tech Studio, we back this with a guarantee: if we cannot make it work after troubleshooting with you, full refund and we cover return shipping.

How long does shipping take?

Car Tech Studio: 1-3 business days processing, 6-8 business days delivery. Free worldwide.

Merge Screens: 1-3 business days processing, 8-12 business days delivery (free standard) or 6 business days (premium option). US only.

How long is the warranty?

Car Tech Studio: 2 years on premium head units. 1 year on modules and Tesla-style screens. Plus lifetime technical support.

Merge Screens: 1 year on all products, with an option to purchase an extended warranty within 30 days.

Final Verdict

Merge Screens is a solid brand. Strong video content, a certified installer network, a longer return window, and deep coverage for popular trucks. If they carry something Car Tech Studio does not, they are worth a look.

But when it comes to the policies that protect your purchase, Car Tech Studio is the safer bet. Customs covered. Compatibility guaranteed. Lower fees. Faster refunds. Guaranteed hardware. Lifetime support.
