You can call it however you like. I put it in my own vehicle years ago after seeing and hearing it in person. I was not even aware at that time that it used the fiber optic system.

I feel like your trying to poke holes in a product that has proven itself in the market as well as users hands. They don't feel the need to give out their hardware details, and I don't think they should have to. I doubt they are interested in having a ton of low quality clones.

I'm certainly not trying to 'poke holes' in the product. I already said I have heard only good things about it. My issue was not with the product but with your attempt to imply that Mr 12V was superior to other solutions because "it uses wifi and bluetooth together". You must know that ALL CarPlay and Android Auto systems use wifi and bluetooth together, so there is no advantage to Mr 12V there, and trying to imply one is at the least disingenuous and unworthy.

I'd also point out that this is an Isudar thread (subject: Isudar Carplay for PCM 3.1), so promotions of competing products may be generally frowned on anyway (although not by me personally) so caution must be exercised.

Enough anyway - people will be getting bored with this to-and-fro I suspect. Good luck with Mr 12V - the big advantage I think you should be promoting is its superior sound quality compared with Isudar. That is not anecdotal or speculative, but easily demonstrated. There is really no need to do more IMO.

Did Mr12V ever fix their graphic banding issue on the screen ??? That looks like S*&*9t. , and in no way better than iSudar.

Hoping for some help ... no power to PCM

Just purchased 2 days ago from Isudar Shopify website. Vehicle is a 2014 991.1 with Bose & Sirius. I removed the sirius cable inside the PCM unit but kept the board

Hoping it is not the harness but getting no power to PCM - not even turning on.

Removed fiber-optic from vehicle harness and it is not attached to anything.

1) Plug the vehicle harness directly to PCM, I can see the fiber-optic light up (red) since cable is removed from harness
2) Plug the vehicle harness to the Isudar harness then Isudar harness to PCM, the fiber-optic does not even light up. Fiber-optic cable is not yet connected to new harness

Been just making sure it is "seated" and tried it a couple of times with no luck. Not really sure how I can test the "seating" more?

Not really sure how to troubleshoot what seems to be the most basic step ...

Note: I had previously installed Joyeauto (with the fuse and everything) successfully in another 991.1 so this is my 2nd install but I am stumped

The fibre optic cable has nothing to do with power, only sound output. It has nothing to do with your issue.

Did you check your PCM fuse? Perhaps it blew at some point.

If the fuse is good, it's possible the Isudar board is pushed too high up and part of it is contacting the DVD player. Remove the DVD player entirely and plug things back in to test if that is the cause of your issue. I had the problem with the Isudar chip contacting the DVD over bumps and it would power reset the PCM. I installed a thin piece of plastic over top the Isudar board and that resolved the issue.

I kept the XM wire harness for my install, but cut off the protruding top part of the connector to make the Isudar board fit. I used the two different length standoffs stacked to install my Isudar board.

Sounds like you are checking the right things. First time I put it in I also had no power. The problem was the power plug wasn't properly seated in the extension harness. I thought it was for whatever reason, and after some unplugging and replugging it went in the right way.

yep the iSudar harness needs a separate power connection and it’s very easy to miss. I’d check all wiring.

The first time I installed mine, I had no power either.

Hey I was wondering: Has anyone tried to add night vision?

I saw this video and it looked super cool:


It’s in the 958 adaptive cruise retrofit thread. Apparently all you need is the camera module and it outputs an RCA signal which then could be plugged into the iSudar easily.

The user says that they used the FLIR camera module which is actually the exact same part used in the 3rd gen Cayenne however he didn’t mention where he got it.

I’ve checked eBay for the camera that user had installed. It’s the same camera for VW and Audi, just different part numbers and the VW Tiguan part was like $300 used.

So I’m considering getting the camera and wiring it to the video input on the iSudar board but wondering if anyone has tried something like this before?

Also, the map display in the instrument cluster is apparently also RCA but I haven’t messed with it yet. Could wire up a Raspberry Pi for some cool visuals. Maybe add a CAN bus adapter for OBD data? Or a camera input and object detection?

I have this project idea that involves a Raspberry Pi (actually another single board computer that has an onboard tensor accelerator chip) and some sort of video input, then reading all license plates as I drive and give an audio warning if a plate matches an unmarked police vehicle. I don’t know how I could get plate numbers for cop cars but it could be crowd sourced or maybe a FOIA request would yield some results?

Im really unsure what is the issue that is you speak of.

The screen shows the maps are crisp, as are videos. The only time there was any banding was on some backgrounds in Pandora.

These kinds of comments only come from users who have never seen the system first hand.

Below are some images from a recent mr12volt install. As you can see they qualify is as high as the pcm screen allows.

It was earlier up in this thread ... the power harness (the big one) was not properly seated .. press it in, then press it in again

chrisgo

Thanks for your reply .. it was the power block (giant one that plugs into the PCM back)

Here is how I was able to get the XM wire out

CaptainSlowly

Thanks everyone that’s contributed to this thread. I found it very useful in getting my 981 Isudar connected.

I had issues initially with my PCM no longer turning on at all. I had to re-connect both sides of the big connector (even though they both seemed fully seated before) and that fixed it.

Much happier with this setup vs the joyeauto I installed on my previous 981 that only had CDR31.



One question I couldn’t easily search to find an answer for : Should I still have my iPhone paired directly to the PCM for phone calls or not?

chrisgo

I removed PCM from my iPhone but have not tested phone calls yet. I do NOT have the Isudar microphone connected and Siri seems to still be ok so I am hoping the phone calls will be ok

Westcoast

No, you should be paired to the Isudar, AA/CP operation to the phone requires that you have the phone paired to it and not the PCM. This way when you are in AA/CP the call control will appear on that screen.

The advice from Zed to avoid removing ribbon cables from the PCM faceplate or the CDR cable from the PCM motherboard has been invaluable. However, his pièce de résistance was his recommendation to delete or unpair the PCM Bluetooth feature from your phone. Simply brilliant! I now enjoy full, two-way, crystal-clear phone functionality thanks to my Isudar CP/AA upgrade. Thank you all, especially Zed—you're the man!
