Great service!

I ordered this radio and immediately received a mail with inquiries about the exact type of my car. After checking with the technician, I was told I would need a decoder to make the radio work properly. I decided to cancel the purchase, refunds were immediately made. Excellent service and sure to be back whenever I need other parts for my car!

Great radio, great experience

This experience could not have been better! The radio’s fit and finish is perfect, looks great. It sounds great and operates perfectly. As a bonus, all my questions were answered in advance of purchase as well as technical help while installing. Khan was prompt and thorough with all responses. Glad I decided to pull the trigger on this purchase!

OEM Fit and Finish with Apple CarPlay in my 2013 MINI

Outstanding service. Great communication. Very responsive to installation questions. The fit into the car is perfect. It does not look like an aftermarket radio. Wireless CarPlay is such a nice feature. Installed this myself and I’ve never installed a car radio before. It was really not difficult at all…everything is designed to be plug and play.

My hole experience with this company and its products so far its been more than amazing and satisfying. I would totally recommend it to anyone that wants an Android head unit.

Customer service is unreal and very fast response and product work as it should with no problems whatsoever.

Mini Cooper

I purchased mini cooper headunit from Sigma, service was five star, Khan was very helpful, he answered all of my questions. Unit itself was plug and play, everything is working as it should. Keep going guys you are producing quality headunits.

Not available in stock does not mean a bad review. By the way you have placed an order for Ford Taurus head unit without confirming compatibility with us, after we asked and you sent VIN and dashboard photo we confirmed that our product was not compatible with your car. We have refunded your full amount. Below copy pasting the email I sent to you (I wish I could attach screen shot here).

Hi Moath,

Thank you for the dashboard photo and VIN. I am sorry to inform you that our product is not compatible with your car. I have refunded your full amount and canceled your order.

Best Regards
Khan

Awesome company & aftersales is perfect

Awesome company, explained what I wanted & was given the choices for my car. Contact through the order & shipping was crazy fast. After sales is perfect, they actually reached out to me after seeing my posts on Facebook about different settings on the headunit. Will definitely use again

What a wonderful experience dealing…

What a wonderful experience dealing with Sigma Car Stereo! I had originally ordered an aftermarket car radio but after talking with Khan was informed that the model I ordered was not the correct fit for my vehicle. After I gave him a few specifications he was able to find and sell me the correct model. It fits perfect and is exactly what I needed and wanted.

Definitely would recommend and would use again!

Bought an Android head unit for my 2008…

Bought an Android head unit for my 2008 mini that didn't have Bluetooth or much in the way of in car entertainment. Now I have it all for a really reasonable price. Happy with the service completely. Price was the best I could find, even rivalling direct Chinese delivery. Ordering process went well, took several days to arrive with tracking number and communication throughout. The only thing that I would say wasn't perfect was the upgrade process for the head unit but after great communication and support everything ended up perfect again in quick time.

All in all I would definitely recommend this place.

I paid for customs and shipping after the ad clearly stated that all charges would be paid. I am yet to get a response re getting reimbursed. Bait and Switch.

Great service and Care.

Unfortunately, the radio I wanted required a bunch of extra things for my car, so I ended up returning it, but it was no fault of Sigma Car. they were great about working with me, to let me know EXACTLY what needed to be done for it to work(because of the fiber optic cable), and once I opted not to do the additional stuff, they immediately processed a full refund. I hope to use them again in the future.

Great sales support

The unit is good and arrived very soon after the order was complete. Unfortunately, the unit did not simply "plug and play" as advertised, and modifications to wiring and additional equipment are necessary even though all of my vehicle information was passed on. The after sales support has been excellent.
