very good product

Works good. The YouTube install video needs to be updated as it’s 2 minutes and doesn’t cover anything. The directions via the web link could also be done better, I understand this is geared for installers, but as a former installer I thought the directions were awful. Once completed the box worked well, overall happy with the product.

Wish there were more vendors. I have to drive 3 hours away and it will be 3 weeks before I can get it installed. Other than that the purchase and cost were great!

It works well, obviously with it being after market it has a few glitches. The only thing negative i can say about it was lack of instruction which made it semi difficult to install but manageable. Proud of final product.

I have recently had the UNAVI installed for my 2014 MB E350. The original MB display got connected to the new CarPlay unit made by UNAVI. Now the dated MB graphics got replaced with the iOS Carplay graphics in full color! Looks amazing! Looks just like a brand new car's display. I hope nothing breaks in the future, so far I am very satisfied! Highly recommended!

This product is awesome ! I have a q5 2016. Just wow !!!

I am excited with the product. I only have one problem, when I use carplay I lose the audio from the car and everything starts to be heard in a small speaker that comes in the kit. that's not nice.

The price of $300 seems fair and reasonable for the install. The entire install took about 2 hrs. Install quality very good. Everything is working as expected with CarPlay. But having issue with Android Auto. I think it’s a phone setting but have not been able to figure it out

Bought the 2019 Nissan Leaf (to replace the useless, brain dead unit that came with my s-type trim). Took about a week to get to me, on St. Thomas in the middle of the Caribbean. Installed the unit myself, took about an hour. Watched the install video and read the PDF install manual first, make sure you do that as that well - will make a big difference on how smoothly the install goes.

Ran into a couple of self-induced problems (bent pin on a connector, wrong bezel screws), the second one caused the LED on the home button to stop working. Everything else worked fine. After talking to Tech Support about the LED they sent me a replacement unit, no questions asked!

Pay attention the the screws you need to use - they give you screws that you'll use in place of the OEM screws you remove. It's pretty clear in the PDF manual (not the video) which ones to use where, but you have to look closely. Make sure you unpack everything and lay it out first, to make sure you're using the ones they want you to use in the places they want you to use them in.

The unit works very well, looks great, and gives me all of the functionality I was looking for. Very happy with the product, the company,

I had serious apprehensions about installing this unit, especially after seeing that I would have to open up the factory touch screen!! YIKES!!!

Actually, if you're even just somewhat mechanically inclined, YOU CAN DO IT! Just GO SLOW and make sure you WATCH THE VIDEOS and pause as you go...I sadly had to contact customer support and (of course!) if I had just simply continued with the video and followed the instructions my "problem" would have fixed itself, as I hadn't completely followed the directions yet.

This kit works just like any factory Android Auto would, but with a couple *tiny* quirks, both of which really don't bother me, because the alternative would be no Android Auto at all. The main quirk is when you're in Android Auto mode, if you want to do anything with the climate control that required the touch screen (changing requested themostat temp, for example), you just need to quickly go back into OEM mode and do your thing...the music, or nav, or whatever will keep doing its thing, and when you're done you just go back to the Android Auto node if you prefer to be there (in maps, Pandora, or what have you.)

The other quirk was that to get the audio I have to have the OEM mode set to iPod mode (or AUX mode in other models)...not exactly an intuitive setting if you're an Android guy, but once you set it there, you forget it UNLESS you want to listen to the radio or XM or whatever other mode you have. Just know that when you go back to Android Auto (or presumably Carplay) you need to re-select iPod as your audio input.

NOT A BIG DEAL, but a small step that isn't necessary in an OEM setting...having said that, I'm very happy with what I have. I bought a 2020 Nissan Armada for $29K and after adding this module and a couple other goodies I am under $30K to have the EXACT same vehicle a friend bought with Carplay/Android Auto for over $70K!!! That's a win!

So, to wrap up this lengthy review: the GOOD:
You get Carplay/Android Auto where you couldn't possibly have it at all. It behaves (for the most part) the same...just a couple more button pushes in certain instances.

The BAD: There is no way to sugar-coat it, this is downright SCARY to tear into your vehicle and then go even crazier and open up the factory touch screen!! BUT, it really wan't very hard at all, and so long as you are not reckless it's really not bad. If you're mechanically inclined or have a friend who is, don't hesitate and jump in and do this. Just go slow, be careful, and follow the directions...even us mere mortals can do it! I've very glad I did!

This unit is the BOMB! Totally professional service, expertly designed, and perfectly integrated into the existing Mercedes COMAND system. I was skeptical of their claims, but after installing this unit in our 2014 ML350 I can tell you that it far exceeds my expectations. If you are a Pre-Carplay Mercedes owner I highly recommend UNAVi to upgrade your ride.

This video was the most helpful. https://youtu.be/uWjPZDu048w Note: You can start the disassembly like shown in the 2nd video, but the rest of the details in this one are better.
The initial disassembly and the re-assembly shown in this one was useful: https://drive.google.com/file/d/11cI2jTfy1-GBVOQ03x1ya6i3PO7PaBgg/view
The wiring clips are more difficult to release that what it appears in the videos. Note that there are generally little release tabs that may be covered by a protective shroud on the connectors. There's not a great video I've found that shows these so be sure to look for the release tabs.
I also used the USB Mount extension cable but wired it to the front cigarette plug rather than the console one to be more convenient.
This did no harm to the original functionality, and allows the OEM equipment to do wired and wireless CarPlay - which Nissan should have supported originally. I'm very happy with how well this integrated.
