Hi everyone, posting a long overdue follow up:
I finally decided to buy the Isudar, had various small issues (ie: needed to buy an MDI to AUX cable so I can set the sound to AUX) but I finally, very briefly got it to work. However when I unplugged the module to start pulling the wires through the glove box etc to hide everything it stopped working and I can't figure out why.
1) OEM radio (inside glove box) works fine when plugged directly into the car.
2) Headunit does not turn on when OEM radio is plugged into the provided power harness (this lets you power both the OEM radio and module). However, the OEM radio is still working as I can get it to play music vie bluetooth, just the head unit is completely unresponsive.
3) Headunit does not turn on when both OEM radio and wireless module are plugged in. The wireless module is actually working as it will start playing music as well and I can hear the click when I switch between the module and the regular OEM radio even if I can't see it switch on the headunit screen.
It doesn't seem like the power harness they provide would suddenly go bad (it was completely working temporarily until I unplugged it again to start hiding the cables in the car) as that it's pretty robust and it's obviously providing power to both the OEM radio and the module. So I guess it's either:
- the power harness actually did go bad somehow
- or for some reason, when the oem radio is connected to the Isudar power harness instead of directly to the car, it's not sending a signal to the headunit to turn on?
Here are some video links I sent to Isudar to try and get some help with the issue.
