I have an Android Auto head unit, now. What to do with the dark OEM screen?

Hey, folks. 2013 GC with Navi here.

I finally upgraded the OEM head unit and replaced with a Kenwood DMX905S Android Auto head unit. This upgrade causes the OEM touchscreen to go dark, because that screen uses a proprietary cable that aftermarket units (even with Axxess modules) can't interface with. So, now I have a dead touchscreen and it's driving me nuts: what are my options?

Sure, I can shove a tablet in there and run Torque.

Could I get the non-Nav LCD in there? That would be nice. If so: what do I need to buy?

Is there a dash kit that deletes the OEM screen altogether?

Is there some sneaky way to keep the OEM touchscreen pumping out all the non-radio info?

Just trying to weigh my options.

after market kit was only for base model when i looked into it a few years ago.
if there's a non-nav screen for bk2, it would be from Hyundai. non-radio info still used the oem radio.
put the oem head back in the trunk and run wires to it?
paint it black?... hang a picture?...

How about some of that fake carbon fiber vinyl stuff? I figure if I replace my head unit (base model) I would use the carbon fiber stuff to cover the top portion so I could still see the outside temp and AC settings. At least I believe that screen stays on if you replace the radio on a base model. Either way, I say cover it up. Maybe stick a Magic Mount to it to mount your phone when you're driving. I have a Magic Mount on my Harley and on the windshield of my Genesis Coupe. I think the previous owner put in an amp and sub because my system's base hits hard for appearing to be stock, but there's no visible sub in the trunk or whatever. I don't have a reason to replace my system just yet, though a backup camera would be great.

Problem is that I have the NON-BASE system with OEM navigation. No part of that stays active when the OE head unit is removed, so I can't just slap tape over the useless part of the LCD like you can on the base model.

Maybe I could just buy the bracket and LCD of the base model and put that in?

Yeah, the navigation screen is bigger than the base system screen, but I figure the vinyl wrap/tape/whatever is a viable option if you do it right, at least even as a temporary fix.

Maybe you could just snag a base model setup. I guess I didn't lose out getting the base model 2.0T since I have the option of a dash kit and aftermarket double din setup if I so choose. I didn't know you guys with the navigation system were so limited.

Can you post pictures of your new head unit? Did you use the base dash kit? I looking at relocating the stock head unit to maintain the AC display on the touchscreen and installing something with Android Auto.

I am curious about this as well. I've been wanting to pick up a new HU for my 13 Track, but I really didn't want to lose the Auto Climate features (I was also under the impression Bluelink would be useless as well, correct me if I am wrong).

Hi, all.

My car is in the shop today having the Android Auto head unit removed. While Blue Link and auto climate control do remain enabled, the 3rd-party interface module that connects the HU to the rest of the car prevents the audio system (AUDIO fuse) and body control module AKA BCM (HAZARD fuse) from every going to sleep. This causes a parasitic drain of >1.5A, which runs the battery to dead in a week.

I strongly recommend y'all stay with the factory radio, unfortunately. This might be different for someone who doesn't have the NAVI unit w/ Premium Audio, but my Grand Touring did not appreciate this project. I cannot have my battery running dead once a week, and I refuse to work around it with a battery tender.

I'm hugely bummed, but that's where I'm at.

Sorry for that bad news but thanks for the heads up. I love our coupes and many of the new cars that are out on the market, but sometimes i hate how they have become rolling computors. It almost seems like you have to be a computer engineer to modify anything these days. Oh well gotta take the good with the bad.

I'm still interested in seeing how the dash kit fits with the navigation screen. I still think this could work by relocating the stock head unit to maintain the climate control screen. As soon as I can afford a wireless android auto head unit I'll give it a try and let you know. Thanks for the info!

UPDATE!

I ended up keeping the Android Auto head unit. We discovered that the Axxess-brand module (interfacing the HU to OEM audio system) was responsible for keeping the BCU and Audio circuits alive when the car was off. So we performed an amp bypass with a Rockford R600X5 and a PAC SWI-CP2 to preserve steering controls. Now all is well!

Head unit works, steering is preserved, backup camera works, no parasitic drain.

I also had the OEM touchscreen torn out and replaced with my Nexus 7 that I never used.

So, let my ordeal be a lesson: Axxess modules suck for Hyundai-Kia, and prepare your wallet for an amp bypass to make this work.

Hey, I'm back! I haven't had a lot of time with my car lately due to IRL stuff, but I did take a picture yesterday.

All in all, everything works awesome. Some other things I/we learned:

1) We fabricated our own right angle 3.5mm audio cable to improve clearance in the area where the tablet is installed.
2) You should look for a charging cable with a 20AWG power wire. Even lower is better, if possible. If you have a MicroUSB tablet like the Nexus 7, this cable worked beautifully for me. Just needed to dremel out the center of a tab on the OEM touchscreen bezel to get the cable into the area.
3) Depending on the orientation you mount the tablet, you may have to dremel out a tiny bit of the dash behind the bezel so it doesn't tag the audio cable.

I did not do the USB OTG thing that people do to load things off of a flash drive. Instead my phone just turns into a hotspot when it pairs to my car, and my tablet wifis to my phone. Anyways, here's a pic!

Well done. I'm guessing you're not going back to stock in the near future...

I'm definitely not. This is my project car until I tire of it, and I would only sell it to someone who understands its quirks and loves it as much as I do.

Thraxbert,

It seems like you are one of the few people to have pulled this off! Everyone I've talked to says it is impossible... I have a 2014 2.0T w/ Nav and would love to do something even close to what you have done. Biggest problem is find a shop to do the work!
No one in my area will touch a project like this.... How did you find the shop that would tackle a project like this?

Thanks man

Hi, @Rumdog . I just called around to a few places and described what I was looking for until I found a shop that was comfortable doing uncommon work.

The Car Audio Shop in Austin, TX (8821 N Lamar Blvd, Austin, TX 78753) did the work for me. And it definitely took some experimentation to arrive on a combination of parts that worked well.

1) It was challenging to find the right USB cable that was the right size + right power delivery.

2) I had to use the ElementalX kernel for the Nexus 7 to improve charge speed. Factory LineageOS kernel was limiting USB current for some reason.

3) Amp bypass was necessary to prevent car-off battery drain.

4) We discovered that the Axxess-brand modules were no good for this car, despite being one of the few options out there. Ended up with PAC SWI, IIRC.

A little dremeling and a custom tablet bracket were needed. But all good!
