Is there anyone knows that I had H3-3D with GCU already, if I buy a H4-3D gimball do I need another GCU for H4-4D spicifically?
(I mean does the H3-3D's GCU work with H4-3D or not?)

Yes, it does.

Hi...thanks for reply

Hi...thanks for reply

Incidentally, both the H3-2D GCU as well as the H3-2D GCU integrated into Phantom 1 Upgrade Kit both would control and stabilize an H3-3D without issue as well so it seems that GCU's are not terribly gimbal specific within the HX-XD family.

Yes, it does.

Hello DJI Support -  Will the H3-2d GCU v1 work with the H4-3D Gimbal as well?

Thank you

You're welcome.

Jamie - I have another question/issue that you may be able to help. I just bought a IOSD Mark ii and received it yesterday. I installed on my F450 with Naza-M v2 and went to upgrade the firmware.

The problem is that IOSD Mark ii is not recognized on my computer. The Com port is created but it does not see the device. I  installed the windows driver but nothing... Also the AV1 is not working. I can see the OSD info on the screen but no image at all.

I did some research online and didn't find much other than people saying that I may have a dead device. It is so frustrated because I called the dealer where I bought it from (www.getfpv.com) and they said they were not able to help and not allowed to take a return/swap neither.

Do i need to send this brand new device back to DJI for service?

Thank you for all the help here.

Could you provide a list of your set up? When you installed the WinDriver, was the iOSD Mark II on and plugged in while installing?

Here is the setup:

DJI Flame Wheel F450
Naza-M V2
IOSD Mark ii
FPV camera connected to AV1 on the cable provided with IOSD Mark ii

Tried on two different computers running Windows 10... I followed the instructions on running the windriver and connected the IOSD Mark when prompted. The installation proceeded and on the driver said no device detected....

As I mentioned I also noticed that AV1 is giving me a black screen with the OSD info on it. I just received my H3-3D today and I am going to install and test with the zenmuse using my GoPro. I emailed support@dji.com but haven't heard back from them.

Once again thank you for the help here.... I really hope is something I can fix on my own and don't need to get it out for repair specially because is brand new and I haven't even flew the quad yet...

What FPV system are you using with this rig? You are able to connect to at least the Naza V2 without issue, correct?

Yes - I was able to connect the Naza-M v2 the only thing is that for the Naza-M v2 I am using my macbook pro... I was able to go through the configuration of the FC with no problems.

For the FPV I am using ImmersionRC 5Ghz for the downlink and a Fatshark Predator v2 ... I am using the FPV camera that came with the fatshark...

Could you happen to provide a picture of how your iOSD is connected to your FPV system?

Hi There - Sorry I didn't reply earlier. The problem has been resolved!! The DJI Support sent me a new driver v3.0 and I used a Windows 7 machine to update the firmware. Success there!

The camera issue was my fault... I powered the camera using the IOSD power output and didn't realize the output from the IOSD is the same as the battery that is connected (3S = 11.1v) and my camera was only rated to 5V I bought a new fpv camera and now I am back in business.

Thank you for the support! The only other question I have now is... where are the Mavic Pros?? I really need one in my fleet
