Just wanted to introduce myself and say hey. I’ll be changing out my OEM head unit in my Tundra here in the next few weeks and will likely need a little help. It’s been about 20 years since I’ve installed an aftermarket head unit so, this should be a blast 🤣! Thanks for having me!

Well, I was hoping I didn’t have to ask for help, but here we are. Head unit is a DMX1057XR and I can’t seem to get it to power up. I’ve checked what I think are the obvious things and the only thing I can think of is it’s awfully strange I don’t have any voltage at the red ACC wire to the head unit. I have 13.57vdc at the yellow constant. I’ve also made sure to install the protective cover that allows the unit to power up. This is everything I’ve used for the install…
Kenwood DMX1057XR
Metra dash kit
iDataLink Maestro RR2
RTO2 install harness
sTO2 GPS antenna retention
SXV300 Sirius Tuner
Maestro 40-LX11 FM antenna adapter
Any help would be greatly appreciated since I haven’t even seen it light up yet. This is in a 2019 Toyota Tundra non-JBL model but still has the crappy amp under the passenger seat.
Thanks in advance!

Check the fuse in the Fuse panel, and make sure the fuse behind the HU is good if it has one. Id start there. If all good. Id pull the HU out and try powering it up at the Battery. You could possibly have gotten the wrong wiring harness??? It happens
