I sent a 2015 Toyota Kluger stereo that kept rebooting to Supertech to repair. Toyota refused to fix it because it was just out of warranty and wanted $thousands to order a new part to replace it.
Supertech were super helpful and although charged a lot to repair it, it was HEAPS cheaper than replacing it with a Toyota or an aftermarket stereo.
It was super easy to pull out and put back in (5mins) after watching their YouTube video.
They emailed to say they had received the day after I sent it, then called to confirm price and time frame then called again less than a week later saying it was fixed. They then sent it via express post, so I received 2 days later.
I was a bit nervous to send my stereo interstate to a company I’d never heard of, and pay before I received it back (hence this review to help out other people), but I’m so glad I did.
I didn’t want to try to replace the factory stereo with an aftermarket one, then try to get the steering wheel controls/bluetooth/reverse camera etc to all work.

Approximate cost: $500
