I have a working Metra harness which works with the factory ML amp and an aftermarket head unit if you are interested in going this route. It works fine; I removed it since I finally did the whole she-bang of a stereo upgrade. Yours for the price of shipping and, lets say, $15. I think it cost me $55+ from Amazon.Damn, really want to avoid redoing the whole thing. Just want an aux plug in. Already bought the speaker refoam kit for all the speakers.

Another thing to try would be see if you can find a functioning, non-Pioneer ML head unit (heck, it may not even have to be ML for all I know) that at least powers on and can work with the BT3 kit. Direct swap if it works too.
In the end, though, I am very happy I replaced the ML system. The sound quality and sonic purity difference was startling.
Specifically, it doesn't work with the Pioneer head unit that is OEM with the ML system in the 01 LX. Welcome to the clubThought I would chime back in for anyone in the future that runs across this thread searching for the same answers as I was. The GROM did not work at all due to the ML system.
By the way, I was able to keep using my CD changer, though I will definitely have lesser use of it.
My CD changer didn't work when I got my vehicle. I installed the GROM BT3. I recently bought a working CD changer from another mud member. I can confirm that you will retain the CD changer and the GROM streaming, at least in the 2003 and newer version LX470 w/ ML. The GROM has a piggyback plug that allows both to work. You push the CD button to toggle back and forth. I did run into an issue on install that was giving me a "external system not connected" message. I tried everything for a couple hours. I finally found that it was the plug for the rear passenger entertainment controls on the center console. Since I had it disconnected to put the changer in it wasn't working. I was trying to make sure it all worked before I put it all back together. Long story short, you need the rear radio controls to be plugged in for everything to work. Hope that saves someone a headache.
Mine would not eject or play. I got it to play a couple times but not eject. It seems like a common problem with them. I think the vertical orientation contributes to the failure. There is a place that will repair them but it was pretty pricey. I got lucky and found someone with a working one. I live in WY and we have big expanses of no radio or cell signal, so the CD player is nice for us.My cd changer in my 06 LC doesn’t work. Did you ever figure out what was wrong with your old one? I’m looking at the grom usb3 and hoping I find a stupid reason for why the cd changer doesn’t work so I can fix that too.
