After several years and 60k+ miles.The dreaded Rav4 gearbox issue was banished never to be seen again.Great people, great service - really know their stuff

Excellent service, quickly diagnosing the fault and repairing an amplifier from a 2007 Mercedes s-class.My only issue is that the total price was more than I had expected. I was driving my car when the repair quote phone call took place so keeping things simple would have helped. Quoting prices without VAT is not helpful.(You pay a fee for diagnosing any faults on dropping off the item. This fee then also goes towards the total cost if a repair is carried out.)When the cost of repair was quoted, I repeatedly queried whether then initial fee would go towards the price quoted. All I really needed for clarity was the final sum to be paid when I collected the repaired item.What I think happened was that the initial fee (which included VAT) was discussed with their repair quote (which, evidently did not include VAT).When I collected the repaired amplifier I paid an further £671 which was much higher than the quoted repair price. I can only assume that this is due to VAT being applied inflating the price by 20%.So allow yourself the time to double check the final cost, particularly with reference to VAT.

Fantastic service A+++++Mark was so helpful with my order for an AV Z1000 DAB CAMPER. I needed the core t unit and all accessories. All arrived on time and correct.I had a bit of a moment with all the wiring to get it up and running. So I called and was put through to a very clear and knowledgeable chap, (sorry didn’t get his name) he watsapp called me and ran me through everything I needed to do. After a lot of procrastinating, I got to it. Fantastic, all I was told worked just fine.Superb service and a great unit.

Really fantastic service helping fix an issue with the touchscreen on our VW Sharan. This led to an issue with our Bluetooth, but this was all resolved by the team without any questions or additional cost. Would highly recommend

I had reason to visit Cartronics Byfleet some months ago after trying several other companies with no success. I had big problems with my Tomtom sat nav. Within a very short time they analysed a problem with the logic & motherboard which they changed. It wasn't a cheap fix but a good lasting one & my Sat nav has been great ever since & I would certainly use them again.Thanks Cartronics

Nice Contact with Mark. BMW Amp works again thanks to Cartronics!

Visited Cartronics today. What a smooth, professional service. Pro logic amp fixed in my BMW M4 within a matter of hours. Very happy with the entire experience.. Will definitely recommend. Thanks guys

Excellent service and repair to my porsche amplifier.

Excellent service. They managed to carry out very complex wiring modifications to integrate a new head unit on my Porsche 911. The showroom and workshop looked clean and well organised. I’m very fussy about my car, and it came back as if nobody had ever touched it, no scratches on the interior. Will definitely use Cartronics again

First class service from them. Repaired Mecedes instrument cluster in no time. Fast and friendly attentionHighly recommend

Great service, they found the problems, some created by other "experts", very pleased with their analysis. Should be your first port of call. 🧑‍💻

Excellent service. New Apple CarPlay fitted to my Motorhome and fitted to play when parked up.( no ignition)Quick, very helpful and informative by email beforehand. Excellent demonstration on how to use.!Thoroughly helpful and lovely people.Highly recommended.

Excellent service would definitely recommend very helpful and honest wish there was more businesses like this one. Thanks Mark really appreciate it

They are very friendly and helpful company. Diagnostic service was very quick and price was fair for full repair service.

A very professional company that responded and helped me quick. Thank you, Cartronics!

Cartronics did a great job with my 991.1 carrera installing Apple CarPlay. Thanks guys. Very diligent and thorough.

Well, after buying a Mercedes E Class convertible in April the head unit failed in 4 weeks rendering the Sat nav, cd, clock, Bluetooth and radio inoperable. This car has had 2 visits to non Mercedes garages and 4 to a main dealer all without success.Out of desperation I contacted Cartronics and they said they could fix it - the first to say that. True to his word Mark got it fixed. Additionally he spoke to our warranty company and consequently we obtained the limit of our warranty towards the repair and reprogramming as Mercedes had ceased production of the head unit. At all times Mark and Cartronics were professional and kind to my wife and I. The work was expensive but they did what Mercedes itself couldn’t. Brilliant outfit would thoroughly recommend them.

Absolut super Service per E-Mail.Genialer schneller Versand durch DHL UK.Produkt passt perfekt für den Mini Cooper S 2005.Alles Plug&Play und der Sound ist der Wahnsinn im Gegensatz zum Originalen Radio.Dank des Iso Steckers wird beim Harman Kardon alles angesteuert.Kann ich sehr empfehlen 🔥

fantastic no fuss repair with a super fast turnround and posted super quick. using a courier with notification of delivery time, so professional. Great service thank you.

Very knowledgeable staff, helped repair a Mercedes cd changer for less than half the price of a new one from Mercedes. Simple plug and play to rest no coding required and expert advice over the phone. Will definitely be using again and recommend to others.

Very helpful, quick and informative replies to messages. Turned the unit around in a few days. Would definitely recommend.

Mercedes S500L W221 Amplifier, not working, common issueOutstanding service, absolutely no issues, no surprises.Highly recommendedThank you

Took my dead BM54 radio unit in and they quickly diagnosed a blown fuse and replaced it over the counter. Could easily have charged me for a repair, highly recommended, great customer service! Will be visiting again in spite of having to travel outside of my current area

Great and easy serviceSpoke to Mark and he explained the process, I posted my BMW amplifier down to him. I was then given a quote for the repair and a couple of days later received my amp back and i installed back into car with no coding required. Worked straight away.Well pleased

Second time I have used this company to carry out work on my motorhome and very pleased each time with the outcome. Trusting one’s expensive toys with strangers is always a little apprehensive but, I found both the quality of work, care and as mentioned trustworthiness, to be exemplary.

We had been waiting for a replacement amplifier (ours had liquid damage) for our 2015 BMW 435 for over 6 months. The replacement amplifiers from the manufacturer are nearly impossible to get. We decided to try to fix the damaged amplifier and found Cartronics. We could not be happier with the incredible service. The amplifier works, the price was fair, and the communication was clear and prompt.

Was losing all audio on my ‘63 reg Volvo S80 Executive some 30 seconds after start up. Several technicians, including an authorised Volvo dealer were relatively certain that the amplifier was at fault but could not be certain. As the amp had to be linked to the actual car, once fitted, it could not be removed, therefore, this was a risky and potentially high cost solution. Cartronics diagnosed the issue with certainty as a failure of the printed circuit module at a cost of some £480 + VAT plus £150 diagnostic charge and the standard £75 for linking to the dedicated Volvo software. Not a cheap repair but far less risky than purchasing a new amp at some £1,200 only to find that it could have been another component that was at fault. Mark was excellent throughout. It did take three weeks to repair, due to the Easter break and accessing the relevant part but patience is a virtue and all works well now. Thank you Mark and the team for a very professional repair.

I had Apple CarPlay fitted by Cartronic on my 2007 Jag XK. I have used the system every day for 2 years without a flaw. The car looks as it did with no unsightly modifications but has modern technology

Super fast service, sent a faulty Harmon Kardon amplifier for repairs. 6 days turn around happy days, highly recommended.

This was a very complex repair and upgrade of a PCM3 system which have been executed to the extent which exceeded my expectstions ! Combined with excellent customer service. My sincere congratulations to Mark and his team.

Including shipping both ways, my water-damaged BMW amplifiers were repaired and back to me in five working days. They really know what they're talking about and offer a great service!

Had Apple CarPlay retrofitted to my Mercedes S-Class, excellent service completed in 4 hours, no mess, great price, what more could you ask for ⭐️⭐️⭐️⭐️⭐️

Super helpful and knowledgeable guys

Excellent dedication to tackling my inoperative Peugeot Coupe 407 GPS, Radio and CD telematics head unit, over 15 years old, no longer serviced nor supported by Peugeot nor the manufacturer. Whilst supply chain issues during Covid prevented their access to parts and electronic chips, a world wide problem, they persevered. They more than fully stood by their guarantee on an after sales issue, which was fully resolved providing me with several options in a very genuine and caring manner. I can now continue to use the vehicle with its original Peugeot unit intact , that no one in Australia would touch, a special thanks to Mark in sales. Sven.

Had a Pioneer Carplay system fitted. Absolutely fantastic service from start to finish. Would highly recommend.

My 2015 Honda CRV satnav/radio failed and the Honda Dealer could only offer replacement at a cost of £4k. Cartronics diagnosed the problem, replaced the defective part and reprogrammed the device to restore all functions at a much more competitive cost. Communications from the company were concise and clear. A professional service.

Excellent service. Informative and helpful, felt comfortable asking what were probably daft questions to an expert in this field.Well priced for a new google play system and reverse cameras for my daughters first vehicle.Very impressed

Straight forward and accurate advise. Steering wheel remote adaptor worked exactly as described.Excellent service.

Had dash cam installed, Amazing customer service ,highly recommend and worthy of all 5 stars

Second time using CarTronics, this time having a new Sony head unit and rear camera installed on my car.Although I know there are cheaper alternatives to complete the installation - I will always choose Cartronics. Their work is completed to the highest standard and I am happy to part my hard earned cash with them. The saying "you get what you pay for" springs to mind.Had a couple of small issues which were resolved quickly and efficiently!Highly recommend Cartronics and will use again I'm sure!

Cartronics installed a Sony (Android Auto) unit in my 2005 MINI Cooper S convertible. It was a bespoke job because the unit is a 2-DIN and the slot 1-DIN, so they had to drop the aircon controls and switch block down the console stack. They did an absolutely first-class job of it. Very tidy, very professional, and a pleasure to deal with. Would recommend without hesitation.

Fantastic service from initial enquiry, booking and installation of new Pioneer Sat Nav & Stereo head unit for my CamperVan. Was a custom trim install, superb integration looks like a factory fit, better than factory! Cheers again all for your hard work. Regards, Ricky

A deposit I had made was returned very promptly as I could longer attend for repairs. Nice to have efficient service.

Thoroughly impressed with the service of these guys, repaired my water damaged amp and posted back, when I had an issue post reinstall, they got me in as soon as possible and sorted this issue. Nothing is too much for them. Will recommend.

Been twice, once for Audio setup to correct a previously poorly installed aftermarket head unit, and once to install some vehicle diagnostic and timing equipment. Very easy to deal with, great communication, did what they said they would, faster than expected. Went the extra mile to deal with manufacturer on an incorrect installation instruction. Small niggle I had afterwards was dealt with promptly the next day. Would be happy to go again

This company is efficient, professional and friendly.I am very happy with the work carried out and can recommend their services.
