Correct, the base shape of the head unit fascia and aircon will not match.

Am I getting the head unit models correctly? Just did this quick comparison based on my search at eBay AU:



Tend to think that (3) would indeed fit. And (4) won't.
They look compatible in the pictures though its deceiving, the GD-03 is a slightly deeper in the lower fascia which will leave gaps on both sides where the stereo meets the aircon fascia.

You can see the height difference when looking at the GD-03 fitted in my car

Here's a better picture of my head unit.



I want the GD-03 so bad, I'm tricking myself to just believe it will fit in my car.

If you're a crafty fellow you could make it fit, make something up to fill the gaps.

I’m fairly confident it will fit ok, as your head unit is exactly like mine was regardless of the air conditioning controls.

If StokeyBry has fitted one with the same setup as yours then you could be in luck, all the small variances between countries makes these mod's so confusing at times.

I'm keeping my fingers crossed for you :fingers:

Anyone found somewhere that stocks just the USB (blue one) that works the Apple CarPlay? I’m sure mines dodgy and need to replace it.

Replied to your msg.

Try running the update again before thinking about replacing components, it's unlikely a cable issue being the problem started after an update.

Sorry I should’ve been more specific. It was becoming a real problem prior to the update it would happen more times then not, but since updating it has been continuous. I think I’ve managed to temporarily fix the lag 2 times but just happens the next time I turn my car off and on. The parts were from a wrecker but my phone and the actual screen are fast that’s why I’ve leant towards the cable connecting the two being an issue. I can’t find the actual part but found something that looks the same, do
 you think it would work?

Today is the first time in months that I've had a whole day out in the car listening to music via CarPlay and I was also getting a lot of lagging when trying to change songs via the touchscreen, must be a bug in the current Apple iOS 15.1 update.

Pulling the USB cable from the AUX module fixed it twice for me today.

some good news.  Another success which can be put down to aux-usb cables that have had a rough life (or rough extraction by the wrecker).  I procrastinated for AGES before pulling apart the dash again for what I feared would be another round of disappointment (and the dash is now a 60sec job knowing where and how hard to yank the panels!).

I FINALLY got around to soldering up a JST cable to a Jaycar female USB cable, and it works!!  My wifes phone was a bit hit and miss, but I think that's because car motion was causing a dry joint in the female pin socket.  So I pulled it apart again tonight to remove the pins (which were a just in case if if I got the pin order wrong) and solder up properly, when Mr Murphy struck and my soldering iron ran out of gas.  Literally with one cable to go, sigh.  At least I can see the end of the road for this journey.

The JST cable.

Hi all

I have managed to get a GD-03 from ebay. The piano black plastic is a bit scratched and there's a small mark on the screen but it cost $350 so I can't complain. It didn't come with the aux/usb assy and cable unfortunately.
I rang Hyundai parts and they can't seem to find the parts based on the model number of the headunit (which I find strange). He suggested I find the year model of the car that definitely has the GD-03 and call back.
Has anyone bought the parts new from Hyundai in Australia? If so, did you take note of the part numbers?? If not, would it be safe to say the 2016 i30 year model definitely had a GD-03? Apparently a VIN number of a i30 with GD-03 would be helpful.

TIA!

UPDATE.

Spent a bit of time on the phone with the local Hyundai parts dept. Apparently you can't buy the USB cable separately - you have to buy the whole dash wiring loom?? approx $4k worth!!  :eek:
He quoted the KIA part number the he found on the net (possibly from here ;)  ) - 96595A5000. He checked with the local Kia dealer and apparently that part number is unavailable in Australia!
Almost bloody impossible to get one!!  :lol:

@jprice46 I'm assuming you already had the correct cable? and that it was just tired?

Ive tried a few wreckers - most have no idea what you're talking about, or, they won't sell the USB cable separately from the unit.

Any other ideas??

Thanks!

Hi legend,

I purchased a GD-03 headunit through Grant Walker Parts.

I was of the undertstanding they were going to send the cabling as well, but they only sent the headunit.

I called them up and asked them for them to send the cable, and they informed me that they would have to get the cable out of a car.

SO it is possible, 4K$ is not true, and not accurate. I would not reccomend buying a cable through Kia or Hyundai simply because those companies charge way too much.

Going through a wrecker is much easier however you have to be pretty demanding and dont be a pushover.

Explain to them your situation, and say that you know its possible because you know they have done it in the past.

Let me know how you go,

Divv

@general2460 my original cable never worked, which started my great tale of woe.

I soldered my own using the pin out and pictures from page 1, a JST cable ($3) from the link above and a USB-A Female from Jaycar ($25).  In hindsight I could have gotten a cheaper usb cable from the JST suppliers.  oh well, still better than the $75'ish quoted through the previous 16 pages of posts for a proper cable)

Dear All,

I've read this great post on how to upgrade to a GD03 head unit and am about do this job on my 2013 diesel wagon.
My car has the OEM parking sensors and after  market camera that plugs into the after market dash cam / parking assist unit.
Would it be possible to run the camera into the GD03 ? would anyone have any info regarding what wires I need to tap into ?
Any help would be greatly appreciated !
Kind regards , Gary

Just joined this fantastic forum to post my results:
I sourced a GD-03 unit from Ebay for about $300 and followed VTHs guide to install. As a lot of people have found, the usb/cable is a bigger issue than installing the unit itself!!

There is a quick workaround though - the cable Teegan linked to on Aliexpress does work. It's also available on ebay sellers with Australian stock for about $16. There are two versions so buy the one that terminates with the usb port.

Then, just plug the cable I to the back of the head unit and run the usb end down the back of the a/c unit and out the bottom of the fascia (near the glovebox) and that's it!!

The only parts that needed to be removed were the air vent trims and 4x screws holding in the head unit
