I too would love wave or google maps on the screen instead. Having Torque (the app using obd2) on screen would be sweet too but that's another story.

Would love to see a good option to replace the CIU which has always been a pain. Fortunately, mine is still working (as much as it ever did). Thanks for your continued efforts and I will wait to see what you are able to create.

Just as a reminding note to everyone.

DO NOT THROW AWAY your CIUs!

I've been able to repair mine by cleaning the board and replacing a few components. My CIU first lost bluetooth, then started to get popping and static tones in the stereo intermittently, then eventually just went black randomly.

I took out the CIU, pulled the board, and found a puffed cap, as well as some corrosion. I cleaned off the corrosion and replaced a cap and a few other components. What I found with mine is that the water ingress caused a short which led to a spike that led to the cap and some resistors to essentially blow.

Once that happened, the trace leading to the input power for my bluetooth chip had no power.

Once I cleaned and replaced those components, my bluetooth came back to life.

The audio hum/static/popping noise I had was also due to the corrosion creating a ground loop. (Or so I thought).

After fixing everything else, the static/popping was still there. The hum was gone, but it was still annoying to listen to any audio in the car. So instead, I isolated the ground and added a suppressing circuit (resistor, diodes).

This eliminated any other issues I had with the CIU.

It is now working. Although I'll probably be replacing it with an Android Auto unit and physical HVAC / Heated Seat controls in the near future. I hate that stupid thing.

Also, based on my experience, "Water Intrusion Fix" did not remedy the solution. So look out for that. Mine had the fix performed twice by Fisker of Atlanta, and water still wicked itself down to the CIU. I'm willing to bet you have to do more to remedy this.

My solution isn't for everyone, but I'll share what I did.

I did two things:
1. Pulled out CIU, sealed the firewall entry from the inside with weatherstripping sealant (used a syringe to fill all the gaps I could see), and prayed it held.
2. Added a water block to the individual wires running to my CIU.

I performed both processes to try and fix this for good.

I also used weatherstrip sealant to attach my windshield weatherstrip (instead of double sided tape). I also added some gasketing around the HVAC opening to help raise the lip a bit and prevent water ingress from burning out that motor.

So far, I have been able to actually drive my car in the rain without fear. While I'm still cautious of rinsing the windshield, or running water into the cowl area while washing the car, I can say that I have been in some pretty substantial rain storms and the car hasn't had an issue.

But with that YMMV.

Once you are sure it is working you should look at potting the enclosure so that moisture does not get in. That is the permanent fix to make sure water/moisture never gets in.

Thats great maybe you should start a side business. Iíve thrown away more CIU then I want to admit to .

Haha I have a box of about 20 wet ones, I should send them to you so you can have more fun...

Thatís awesome @latimer! Yes - Letís get some functioning replacement CIUs! Hopefully these all last until a longer-term solution is ready.

Personally, Iím willing to seal any area I can to try to prevent the water instruction and hopefully alleviate one more cause for concern.

On a side note, @FiskerPhilly, would you be willing to send one of those bad CIUs to someone like me? If so, what would the cost be?

I would think @FiskerPhilly would be happy to pay you to take them off his hands.

During the most recent Karma event in Los Gatos, one of the Karma reps told us that they are looking for a company to refurbish the CIUs, which sounded like a great idea. Does not seem like they made a lot of progress.

I'll look into that as well...

I'd definitely be interested in seeing if my solution was unique, or if this is universal.

I'm sure some will be worse than others, but if I had some dead ones to test with, I wouldn't mind seeing if I could revive them.

Shoot me a PM if you are willing to send some along.
