"Mercedes CLK350 car play"

Purchased a replacement head unit for our Mercedes CLK. It solved all the issues we had with the audio system. The process was effortless, delivery the United States with out issues. Thank you.

"Bon commerçant"

Bon commerçant, La commande est arrivée conforme et fonctionne. Je recommandes ce site pour ce genre d'achat. Bien écouter leur demande pour la compatibilité, et le suivi du colis est sérieux.

"For sure you will get support, if will be needed"

Was small delay with delivery, but Sigma team (Knah) informed about it and was asking if it is ok or send money back. Once radio arrived, all plugs and converters were included, later via mail was delivered manual and connection drawings. All was fitting without any problem. I can really recommend Signa Car shop.

"Kahn was super helpful"

Kahn was super helpful! Sold me exactly what I needed, but made sure first that it was the radio that my Toyota Prado needed! Being super meticulous with every detail! Thanks you for everything!

"What a fantastic experience I had…"

What a fantastic experience I had dealing with Sigma Car Stereos. Communication was excellent and exactly the right head unit arrived here in NZ within 4 days of ordering.
I couldn’t be more happy. Double thumbs up!!

"Total commitment to Customer Satisfaction"

No question that Sigma have a total commitment to service and customer satisfaction. They (mostly Khan) were very responsive and helpful during the installation of an Apple Carplay system for a 2011 Maserati, i.e. a customised system. After some early installation glitches, which might have been helped by more up-front information, it now works well. The product is very good. However I have to workaround a couple of physical switches on the dashboard due to a slight mismatch in the configuation. Not a major and I would certainly use this company again if the product proves to be reliable. So far, so good. Thanks Khan

"I just mounted the screen and the…"

I just mounted the screen and the camera to my car, All parts came in the package as promised, including the wireless CarPlay which I bought separately. Excellent and professional customer service, They responded immediately even weekend night and helped me a lot with the installation. I highly recommend this company and its products.

"I have bought two units off Sigma car…"

I have bought two units off Sigma car stereo. Both for Mercs. The units are not fully plug and play as described. I had to liaise on numerous occasions for issues, that included needing wires spliced and general installation difficulties. Yes, Khan provided answers via Whatsapp but these products do not have complete OEM functionality. For example I can no longer adjust the clock in my E350. The products look good but I won't be buying from here again.

"Car radio/GPS perfectly adapted to Lamborghini Gallardo"

The car radio/GPS with rear view camera works perfectly.
The unit blends beautifully with the Lamborghini Gallardo's dashboard.
Thank you for the availability and technical support.
The supplied car radio and technical support deserve a 5/5 rating.
Many thanks again.
