Hello, Please contact our support team via email or whatsapp. Trustpilot is for the customers’ reviews. We don’t know what order you are referring to. /Björn

Thank you very much

In general, I'm pretty happy with the product and customer service. I learned that the communication over WhatsApp is more efficient than email. I wish guys would provide better documentation especially on head unit plugs definitions and pinouts including Canbus, it would make my installation much faster. Other than that , everything works now and thank Sigma Car Stereo Team.

Dear Vladimir, Our tech team is always available on Whatsapp, email, WeChat, YouTube and facebook messenger. We have more than 1000 models and we do have a pinout and plugs definition for all of our units. We also have installation videos and photos for many of our models. We record videos as soon as we get a chance of a new model car.
Thank you for your honest reviews. We hope you are happy with your purchase.

Bought a unit for my bmw

In reply to your reply

So let me get this straight
You sold a product with a manufacturing and design fault
And your idea of service and quality
Is to tell the customer to fix it himself
Because that’s the cheapest for YOU?

Customer service

Ordered a stereo for a mini. Did not notice where you should click to add CarPlay so had to get the dangle to connect. Your stuck buying their very expensive dangle as it’s the only one that works with this stereo. Tried to work around this without success or help from the company. Got the dangle with no app or link to the app. Sent multiple emails to get the app and received a link that went no where. Now I get no response nor the app and have paid a lot of many for something I can’t use and a stereo I can’t use as intended. Was planning on ordering another stereo but after this ordeal I will order nothing.

Dear Cory - If you did not notice where to add carplay from that’s not our fault. After we ship the head unit it’s not possible to add built-in carplay. There is no way to integrate the chip inside the head unit. You have to use dongle via USB port.
And what???? You have sent us multiple emails but no reply? We have a team of professionals replying on whatsapp, emails, facebook, instagram etc. Our last email was that we sent you carplay app and after that we haven’t heard anything from you. If you have any genuine issue please contact us and we will try our best to solve your issue. If we could’t, we will make a refund. After your reviews here, we sent you multiple emails asking about your issue but you have not replied to any of our emails. We have thousands of satisfied customers and we don’t leave any issue unsolved, nor we leave any email not replied.

I purchased an auto media system for my Fiat 500 from Sigma Car Stereo. Th customer service was excellent. They answered the myriad of questions that I had before my purchase. I bought the system from them at a reasonable price. It was delivered to me very quickly. It was completely pre-wired with a plug and play harness. It took no more than an hour to install. They answered some questions immediately about the installation. Now it is working great. I highly recommend Sigma!

Great product, great support.

I don’t leave reviews unless I’ve had very bad or very good service. The service from Sigma has been spot on. They answered a lot of questions up front to identify the right head unit and then supported me during the install by answering questions via the WhatsApp link on their page. Can’t fault them. Head unit was for an Mini Countryman R60.

Purchased a radio upgrade for our 2009 Mini Cooper from Sigma Car Stereo. The experience was excellent! Extensive information provided on their website about available products, along with very detailed photos and descriptions to ensure customers select the correct product configuration. Communication with the company staff was also outstanding. The product arrived promptly and fit perfectly after installation. Our 2009 Mini now has up to date technology that works beautifully. And a backup camera was included for free! All in all an excellent choice!
