Looking for solutions: Navi and audio system in the 2015 Toyota LandCruiser do not work

Hey, I had a similar problem with my 2018 Toyota Yaris. The air conditioning didn't work and neither did the electrical equipment. In my case, it was the cable connection that was faulty. At first glance it seemed simple, but unfortunately the failures would keep recurring until a buddy of mine, who is an automotive mechatronics engineer, took a good look at it. It was a serious issue that required a detailed examination of the entire wiring system to find the cause of the problem. I would advise you to find someone who really knows their stuff. A fault in the cable connection can easily be overlooked and that could cause more problems in the long run. Hope this helps!

Hey, wow, the cable connection catcher sounds really nerve-wracking. I'll definitely try to find someone who knows about it. If it's no trouble, could you remember how much you had to fork out for the repair? And have you had any other issues with your Toyota since then that caused you to have to have the entire wiring system re-examined or even replaced? Thanks for your help!

Hey, I can still remember that the story with the cable connection back then really threw a spanner in the works. But since then everything has been tip-top again. I contacted a specialist back then who fixed the cable connection error. It wasn't cheap, the little thing cost me 155 euros, but everything has been working perfectly ever since. After the mechanic's visit, this annoying problem with the signal error in the audio system was also solved. Since then, I've had no more problems with my car - everything runs perfectly. Maybe you're lucky and it's just this one fault with your car. The cost is annoying, but it's worth it if everything works again afterwards. Good luck, and let us know when you've found a good mechanic!

Hey, thank you for your detailed reply and the good advice. Of course, 155 euros is a lot of money to start with, but if it solves the problem permanently, it's definitely worth it. My wages will arrive next week, so I'll take your tips to heart and look for a competent specialist straight away. If I have any further questions or find a good mechanic, I'll definitely get in touch with you again. I really appreciate the help! Thanks again and have a nice evening! Bye!
