For those of you looking for a wireless CarPlay solution, I found a solution that works well. I had been doing some research on how to deal with the slow charging issue when using CarPlay as the USB ports on the EC Offroad and other units like NaviPlus don't deliver the power needed to keep up with constant use of the phone. In the process, I stumbled upon the Carlinkit product line. They have various options that are designed to add wireless CarPlay to factory head units, and add wired or wireless CarPlay to Android head units. The requirements for the wireless CarPlay product for Android head units are pretty minimal - you need to be able to install apk files, have an available USB port, and be running Android 4.4.2 or higher. The EC unit easily meets those requirements.
The product I selected is available on Amazon with Prime shipping and free returns. There was also a $10 off coupon available when I purchased mine. Here's a link to the product on Amazon:

Since sending it back would be easy if it didn't work, I decided to give it a shot. It arrived yesterday afternoon, so I haven't been able to test it extensively yet, but it is working fine so far.
- It took me about 5 minutes to get it up and running, including downloading and installing the required app.
- Startup of the CarPlay screen is fast. I think it's faster than the ZLink app that EC Offroad includes for the wired solution.
- Apple Maps navigation audio worked perfectly on the first try.
- Music through it worked perfectly on the first try.
- The Info button works to tell Siri you want to give it voice commands.
- The next/prev track buttons on the steering wheel work
I did have a minor issue this morning where audio from music apps wasn't playing through the car speakers (navigation audio was fine), but I've run into that with zlink as well. Reconnecting the phone to the app resolved that. I'm pretty well convinced this is an iOS issue as I'm pretty sure I ran into this a few times on my Mercedes that had CarPlay in the factory head unit as well.
By default, the Carlinkit app runs at startup, so the EC unit currently starts up in wireless CarPlay mode every time the car starts. I know this can be modified in the Carlinkit app, but I haven't found a way to get an icon for the Carlinkit app to show up on the EC unit's apps list. Until I sort that out, I'm going to let it continue to start up every time. It's just 1 button press to exit back to the EC unit's home page anyway.
So since I've had it for less than a day at this point, I'm not going to encourage everyone to go out and buy this yet, but the initial results are promising.
UPDATE:
After using this product for about a week now and receiving feedback from a few others who have tried it, I'm giving this solution a big

.
The only potential issues I've seen so far are:
- Once in a while when playing music, it won't play on the factory sound system. I found that if I check the control center on the iPhone, the problem is that the phone has selected another device for audio. Switching the audio selection over to "CarPlay" will resolve the problem. There's no need to exit CarPlay or take any other action. I'm pretty well convinced this is an iOS issue as I've run into this with other CarPlay setups, including in the zlink app that the EC unit uses by default for CarPlay.
- When the Autokit app apk file is installed, it doesn't add an icon to the EC unit's launcher app, which makes it a bit difficult to get back to CarPlay if you exit to do something else. There are a few solutions to this:
- Setup the Nav button to launch Autokit in the EC unit's home page setup.
- Install the "Simple App Launcher" app from the Google Play Store. Once this is installed, you can add and remove apps from this launcher, with Autokit being one of the apps you can add. Note that this isn't a full launcher replacement and has very limited features - apps are displayed alphabetically with no option to sort them any other way. But the display is very simple / uncluttered, which is good for a car.
- Install the "Nova Launcher" app from the Google Play Store. This gives the same benefit as "Simple App Launcher", but is far more configurable and can be setup as a full launcher replacement if one wanted to do so. But be careful here because replacing the EC units default launcher would make it difficult to get to the EC unit's setup pages to do things like install firmware updates and modify some of the audio and display options.
- I have done all 3 of the above for now. I'm not sure if I'll keep both "Simple App Launcher" and "Nova Launcher" installed long term though - I need to use them more to see what I prefer.
After using it for a week, wireless CarPlay is a huge game changer. I had been saying that it wasn't a big deal to have to plug the phone in every time. I was wrong. Now that I don't need to even unlock my phone to use CarPlay, I'm finding that I'm using it all the time on short trips because it's so easy. For longer trips when I need to worry about keeping the battery charged, I can now connect it to the charger of my choice to keep the phone charged.
