Also something interesting while the car is not driven I noticed that the battery tender was charging the battery more than usual. Like there is a power drain. Any ideas about that? Thanks again.

There were a lot of connections made when installing the Isudar kit, if one of them were 'just' solid enough it would not be inconceivable that something might have wiggled loose. Trouble shooting has to begin somewhere, have you reached out the Isudar? They may have a suggestion where to start.

I have pulled out the main PCM fuse to see if the battery drain continues before pulling the unit out again to troubleshoot. Thought I'd ask the community to see if someone has an idea since it was working fine for a few weeks and then not using the car for a week it stop working.
Thank you for your replies and suggestions.

There are some good ways to detect parasitic battery drain which we can go into later, if the PCM doesn't seem to be the problem. First though, we need to rule in or rule out the PCM. First rule of troubleshooting is 'look where you last worked'.

Also, if I were going so far as to pull out the PCM, I 'would' be checking all internal connections I added or touched during installation as part of the 'blank screen' issue.

They did not address why my unit is completely dark with no display or sound or how to fix the issue. I can not even update the firmware they gave me if my unit does not even turn on. I have yet to hear back on that and have not had time to pull the PCM out to check anything.

Hi all. Thanks for everyone who posted which has helped me in deciding to get the isudar board. I've all the post here and other threads to get mine installed. I am hoping someone may help me with my issues. Everything works on my install even with the xm board making it tight. My board is a v3 with the 230703v1 gr00 version. My issue is that my aftermarket backup camera would cause the pcm to not display the camera sometimes and basically resets the isudar board. I would have to select the 360 camera option in the backup advance menu before the backup camera would come back on. However sometimes the screen will just turn blank or black but the PCM radio would still be playing but can not be controller. I would have to pull the fuse of the PCM for everything to come back on and I would have to change the 360 camera option on and off for it to work but then after a while the cycle continues. Any help would be greatly appreciated. Thank you.

Board version v3 huh, you didn't happen to take a screen shot of the build/version levels while it was still operating?
