Aftermarket head unit won't turn on ML amp.... (2 Viewers)

The non-nav conversion adventure continues...

Vehicle is a 2005 w/nav. I've completed the non-nav conversion and it works great.

I'm trying to install a new head unit from Crutchfield with the TYTO-01 adapter. I cannot get sound out of the speakers. For some reason the amp is not turning on. I've been on the phone with Crutchfield for hours and they don't have an answer. I've gone over the wiring instructions multiple times.

Everything works with the OEM head unit. I set the volume, fade, and balance before disconnecting.

I know the head unit is working and putting out signal on the speaker wires. I have constant and accessory power going to the amp. All the fuses are good.

I've seen other posts where people use regular aftermarket headhunts (i.e. not Teyes or Android) with the stock ML amp.

Is there a step I'm missing to get the amp to trigger?


Thanks.

Solved my own problem...ordered another TYTO-01 of Amazon, replaced the one from Crutchfield, et voila, sound!
There is a data signal that the TYTO generates to turn on the amp, per Crutchfield. I guess that was the one thing not working on my original part. I don't know of any way to test it, and Crutchfield did not either.
So for the record, you can install an aftermarket head unit (Sony, Boss, Jensen, etc) into a nav-equipped truck, but you must do the non-nav conversion and use a WORKING TYTO-O1 adapter.
