GROM Audio UK Opiniones 

Perfect works well and great technical support as well.

I am so impressed with the system, a USB3 + Bluetooth dongle. I thought it would be good but it has exceeded my expectations. It's brought my car's 17-year-old ICE into the modern day!

Excellent customer service and super fast delivery of the Bluetooth kit for my Lexus 400h. I love my car but for years it has frustrated me that I can’t stream music through the fantastic sound system that came with my car. Well I can now and I’m over the moon, and it only cost me £130

Please avoid. - If you've got an Android phone, do not listen to their attempts to tell you this device is supported. It is certifiably not.
They have lied about having an app on the Google Play store, but they do not. Do not install the APKs they will send you. Could be malicious, and the application will not work, and may steal your credentials when asking you to log into apps.

Their customer support is non-existant, calls and emails asking them to confirm it's support was met with lies, then they further lied after I installed the unit to say that it actually only supports Bluetooth streaming (VERY LOW SBC QUALITY).
They have stated there's no plans to support existing and new Android users, and they will not respond to emails requesting for a return label.

Do not spend money configuring your car to get this to work, if you have Android, they will be happy to take your money, then tell you you're at fault for owning one.

I have call recordings, emails, screenshots of their website, and "wayback" archives that show their site continuing to advertise USB audio, when it does in fact NOT work. They will not be supporting this device, but are happy to continue selling and purchasing more stock.
Worked as a developer and electronics engineer for 15 years, asked if they could provide me information on the device to see if I could personally get it to work, they would prefer to not help at all.

Thanks Richard, £400 on the device, and a car config change for absolutely NOTHING.

Just buy a decent quality LDAC or APTX bluetooth adaptor for less than £50 and use your existing AUX. It's not the best, but I'm sorry, they do not care either way.

No USB audio support, no bluetooth steering wheel controls, no further firmware or app updates, and no support whatsoever on calls or emails. - All certified and justified by Richard @ Grom Audio.

Tried a cheaper alternative, my advice don't bother! Ordered the grom BT kit, arrived quickly, easy to install, works flawlessly, well worth the money. Thanks very much guys!

Had a problem with one of my wires but Richard on the other end sorted it out just fine. great company :)

Ordered a bluetooth box for my old car. The sales team answered questions promptly and sorted out refunding the vat on the export order. The order came in two days and the Grom box was easy to fit and works a treat.

I have just bought my 2nd device (bluetooth pairing with phone calls/mic) for my Subaru Forester. Took a couple of attempts to pair, but now sticks every time. I also ordered the 3mm jack and phone charger/connector which covers all bases.
Delivery was fast.
Fitting was really easy. Mic was a bit awkward to hide, but got there in the end :-) but that was to be expected.
I already had trust in GROM devices after fitting one to my Lexus RX in 2015 (non-bluetooth), which is still going strong. Team were helpful as I was on a 2003 facelift plate and they contacted me before dispatching to clarify if I'd ordered the right connecting cable for my year/stereo (which I had) but it was good to know they were conscientious and thorough.
I generally don't use the app as everything seems to work without it: Google Maps, Spotify, general streaming, iPod devices, etc
Would happily buy another.

Carputer-shop / GROM audio UK. Product was first class, plug and play, easy to fit following instructions & YouTube videos.
Was Bluetooth for a Volvo S60 2005.
Customer service was top quality, replied to me swiftly following no order confirmation email & sent out next day delivery. Would use again & recommend!

Asked for help to find right device for my old lex to have aux. Quick answer and full support when buying and installing product. I dont know how but ita working amaxing with nice quality sound and i have all my original options like cd changer. Thanks. Very rare to meet that level of service in uk.

Ordered a Grom USB3 for my Volvo V70 and received it within a couple of days. I wanted it for mp3 playback and wasn't bothered about Bluetooth phone connection. I didnt remove the head unit instead i connected it into the rear of the car via the rti unit.Very easy to fit as it comes with vehicle specific cables. I followed the instructions for the folder structure on the mp3 drive and it worked straight away. The steering wheel controls and reversing sensors all work as they should as well. Sound quality is excellent and i have 40 albums in mp3 format @ 320kbs on a 8gb drive. Its early days but so far i am very pleased.

Cant fault the customer service but the product is hit and miss. Some days it works, others it doesn't.
Just connected phone and using dashlinq but it will only play through phone.
Very disappointed as this was a 65th birthday gift
