Apple Car Play / Android Auto using stock display and controls!
Hey All,
Haven't been on in a while which means so far so good with my XKR. Hope the same is true for you other old timers on here.
Anyway, I thought I'd share something that got me pretty excited when I saw it on one of the Facebook XK pages this morning. I've been wanting to add Apple Car Play for a while now but didn't like the thought of altering the original display or functionality of the steering wheel controls. So I was instantly intrigued when I saw the following intro and installation videos from an outfit called Mr. 12Volt:
I've gone ahead and ordered one on pure faith and will report back when I have it installed but was wondering if anyone on here has already fit one.

Installed!
I'd hoped to post this update a lot sooner, but due primarily to my own ineptitude, I spent the last few days installing, uninstalling, then reinstalling the Mr12Volt unit I received over the weekend. Just before my first attempt, I saw a post by someone on the Facebook XK group saying they may have irreparably destroyed their display. This naturally added a bit of anxiety, but I figured I'd just be extra careful not to damage some of the connectors on the circuit boards as the poster had done. Of course, I immediately ran into one of the problems he described which was an internal power connector that crumbled in the course of being unplugged. But this turned out to be a non-issue since the broken cable and connector are replaced by a new one anyway. I take my time, and two or three hours later, I fire the car up only to find a blank white screen. I double check my connections against the install video and everything seems to be right until I notice there's a cable in the video that I don't seem to have. I rewatch the video over and over and wonder if perhaps Mr12Volt didn't account for different generations of head units. I message another user on the Facebook group who successfully installed his unit, and he confirms his OEM head unit and harness have the connector I don't. I uninstall everything and am relieved to see my original head unit at least works again. The other user from the Facebook group mentions to me that he also ran into a white screen initially but found that he had improperly connected one of the ribbon connectors. I decide to take out my head unit again and reinstall the Mr12Volt unit taking extra care this time on the ribbon connectors. Sure enough, I must have done something wrong the first time around, as I'm happy to report I now have Carplay, etc. on my 11-year old car. I'm still figuring out how it all works, but I will say the sound quality is great, and there's the added bonus of having a temperature gauge if you have an OBD app installed on your phone. The OEM screen's resolution is better than expected, but touch/swipe functions are a little slow compared to modern devices. Overall though, I'm pretty pleased to see the unit working as described after some self-induced panic. Below are a couple of screen shots of the unit in action
A couple nuggets of wisdom from my installation ordeal:
- Empty the CD changer before uninstalling the head unit, as you may end up with some stuck CDs in the course of removing and moving the head unit around
- Be aware that some of the 10+ year-old plastic connectors in the head unit's circuit board can get brittle, so be extra careful disconnecting them (for me, this only applied to the tiny two-pin connector between the two boards)
- The ribbon cable connectors on the OEM boards and on the piggyback board that come with the Mr12Volt unit all have different locking/unlocking mechanisms, so familiarize yourself with how they all lock/unlock first. I suspect my mistake my first time around was not realizing I hadn't fully locked one of the connectors on the piggyback board, and one the ribbon cables wasn't squarely in place
The OBD app I have shows gauges on my phone but on Carplay only a couple of PIDs get displayed. But hey, it's better than nothing!

It the AUU (iPod) module. Here is an install on the XK.

This walk through is of a different system.

No, it uses the USB port not the auxiliary port. There are 2 different systems being discussed above adding confusion.
The system using the auxiliary port requires a software update to expose/activate the port; this is a system designed years ago. The new system introduced in this thread uses the ub port.

This thread is so timely as I stumbled across Mr12volt just yesterday. Not sure I quite understand the USB connection as I don’t have the Ipod interface in my base system although I do have the bluetooth connection through the Aux input.
Appreciate the initiative and feedback from the early adopters.
