Nice upgrade for legacy entertainment system

I am very impressed on its functionality at such low cost. After installed, the CarPlay functioned is very similar on my new car except the phone call function cannot be controlled on the steering wheel. Wrote a message to customer support, they just replied one page of the Bluetooth setup which is not on the installation manual comes with the unit; and it fixed the issue I had. Very happy to have this RoadTop decoder upgraded on my 2017 Lexus ES, and the tech support must be very familiar with the issues to resolve right away.

Skeptical at first, but WOW

2015 Lexus ES300h. Installation was surprisingly easy and the unit works BEAUTIFULLY. I wish that I could unlock it for additional functionality, but it runs and looks great. Inititally I was struggling to get the wireless Android Auto to work, but once you plug it in, it sets everything up and retains the settings. Now I start my car and it wirelessly connects and runs perfectly. AND I can choose my audio and video INDEPENDENTLY - I can play Satellite radio while I'm seeing my google maps, etc. Incredible bang for the buck. Shipping was FAST too! I had it delivered to my home in Canada about 8 days after my purchase. Best money spent on my car.

2018 RX350

Was nervous removing the plastic trim but following a few YouTube video’s actually wasn’t bad. Install was straight forward. Tech support was great. Ended up updating the firmware and they answered multiple questions. For the price this CarPlay is great. Been working well so far. Previous review did not post for some reason. I would recommend this upgrade even for not having to pay for map updates from Lexus.

I was skeptical to see how this would work on my 2015 is350 f sport. Install was very simple. Hardest part was probably putting every thing back together neatly. The product works exactly as advertised and is actually very smooth. I am surprised because stock navigation is pretty glitchy so I didn’t think it would work too well but it works amazing. Highly recommend buying this. Be sure to also go through settings and change a few things to get the best experience. I will be buying one for my dads tundra as well

Best option for adding Android Auto or CarPlay to your JLR

Let's be honest: You're considering this because it's the cheapest of the boxes that offer this capability. And it delivers. I was skeptical, too, but it was less than 1/3 of the price of the "name brand" competitors, which all seem to do exactly the same thing. So I rolled the dice and purchased directly from Road Top for $209, including shipping. Shipping was fast. Only about 4 days to Iowa. The packaging and device build quality were both very good. Cable looms are well made and well pretty well labeled, but really it only plugs in one way because each of the connectors are unique, so the labels aren't that important. The only issue I had was with getting the main connector into the head unit was very tight. I shaved a touch off the top of the clip and added a bit of silicon grease on the high spots and that helped a little. The instructions provided were high quality with lots of pictures and a QR code to how to disassemble your interior. After you get everything plugged in, make sure you test it before putting you interior back together. You may have to adjust the DIP switches to get it to display correctly (all well described in the provided instructions), or, as with my case, it may not display anything at all....
Tech support. I was not happy that it didn't just work right away, and the troubleshooting guide didn't address this issue. I emailed the address in the order confirmation email and sent some pictures and a link to a video I took showing the issue. If you need support, take pictures and video of the issue. Tech support is in China, so be prepared to wait overnight for a response if you are in the USA. Responses were in very good English and were clear and helpful. I think the video was the best thing I did to facilitate this exchange given that I had a non-standard problem. Tech support suggested a couple of things from the troubleshooting section of the manual, which I'd already done, but they also sent a very small (39 KB) ZIP file that contained a firmware upgrade. The upgrade was easy, just unzip the files, put them on a clean FAT32 formatted USB drive, and then boot the Road Top box with that plugged into it. Wait 5 minutes, then unplug the USB drive and reboot. That upgrade is what fixed my issue, which honestly surprised me. The remaining configuration setting within the device interface was very easy and covered in the instructions. Don't overthink this, just follow the instructions even if you think otherwise. It works like a champ. I put everything back together and it has been great. The only issue I had is that the WiFi channel programmed for use in the US is channel 6 which is used by everything. I was getting interference driving through neighborhoods, at traffic lights, everywhere. I changed to the Europe setting (136, I think), and it is much better. Don't tell the FCC. But you can do all that through the interface in just a few seconds, so you don't have to take the interior apart again.
Functionality. The only things you give up when installing this are the factory navigation (no problem, you want your phone nav, anyway) and within Android Auto or CarPlay, you can't change tracks with the steering wheel controls (volume and phone controls on the wheel work fine, and the track buttons work if you are listening from any other source than the Road top). That's it. You can still use the factory bluetooth for calls or music if you want. The factory backup camera works like normal, as do the park assist functions. It changes between factory screens and AA or CP screens seamlessly. All the stuff in the 4x4 and "Extra Features" sections of the factory infotainment system work great. The Road Top box has an EQ built in, and you may want to adjust that to get good sound quality through CP and AA. Good luck!
