Its a sharp 8.8" screen, buy one from Ebay and swap it

Hi Blue Dragon, what are your thoughts on the Avin system? Did you look into it before doing your CIC retro?

Thanks

Do you know which model they use, is it the LQ088H9DZ01? Cheers

Sorry not familiar with it. I did my retro back in 2013.

I did a 4 hour road trip last Saturday. At about the 3 hour mark, my wife needed coffee, while I needed a lavatory. Walked back to car and started it. Screen was RED for about a minute and then went black. I'm thinking here's another $1,000 bill I was not expecting. Handed my iPhone 8plus to my wife and said try to find anything like "E70 black screen repair", after a few misses, she said I think I found what you want. Sure enough a guy from the UK described the exact same problem and a fix (don't know if the car was also from there). Anyway, we drove using the SOUND of the GPS lady, plus the iPhone map route which matched turn for turn.

Here's what he demonstrated.
First, shut off the car.
Next, turn the headlights on
Finally, disconnect the two cables from the battery in the trunk, I had to pull a twisted yellow/black wire that was held by a rubber grommet which took a minute, plus my son has no tools so I had to use what he had to pop the clip on the RED side then I simply loosened the black side and confirmed both were unable to touch their respective battery terminals. THEN I connected the two cables together and waited about 10 minutes. Put the cables back where they belonged (Yes, the battery is less than 5 years old, and there was no white "cocaine" on either terminals or cables. I clean them up and replace the red and green electrolytic inhibitor felt washers at the same time). No lights appeared on the dash either

10 minutes later - BINGO!! I did not lose any presets (including my phone book and Sirius radio stations), the screen came up and I momentarily had a message about a problem with traction control that disappeared.

I'm delighted that my wife found a fix that worked on YouTube, and it is an '11 but has slightly more than 50,000 miles on the OD. The only thing I could come up with is that there is a plate on the RED side terminal with a variety of wires, held down with screws, which holds in place about 6 or 7 wires which I can't find on REAL OEM. If I were to guess, it reminds me of a voltage regulator which the last time one of those went bad, I was driving a Chevy Monte Carlo and Jimmy Carter was president.

I'd really like to know if anyone had a similar experience and should I be putting some cash away for when that part, or some other part, yet to be determined goes bad. This was last Saturday 8/22. Started and stopped about a dozen times since then, without a failure. Ghost in the Machine?
Thanks
