Per title, I'm in the process of installing a T'eyes CC3 in my 2006 LC100 which has a JBL nav/sound system. I tried a Grom Vline2 for a couple weeks but using the original display just isn't cutting it for my aged eyes. My questions are related to OEM connections. First photo is of the two antenna connectors. So, why 2? The original location was on the back of the JBL sound unit. Unclear where they might go on the CC3. It has one antenna port but the larger OEM connector is smaller than the port on the CC3 (and smaller than the antenna connectors that I've usually seen). The other OEM connector is even smaller. Is the smaller one video from the OEM backup cam?

Next pic is of a two-headed connector that was not connected to anything when I installed the Vline. The two pieces mate so it makes me think they are a feed-through wire bundle. I think the other end feeds back to the computer behind the glove box.

So what is the function of this cable assembly?

Making progress on the T'eyes install actually. The unit does seem to control AC correctly, steering wheel controls work, bluetooth good, Android Auto working, and the display itself is crisp and clear. I do have the "hiss" as reported in other CC3 threads. I suppose a new amp is in the future, but I'd like to get the radio working, even with the hiss, before going that route. (I thought I came across a backpanel schematic for the OEM JBL system somewhere but can't seem to find it now. If anyone has a pointer to it, thanks.)

So, TIA!
 
Some years of the 100 have two antennas. You can either use just the big one or combine them with adaptors like these:


Not sure what antenna inputs the Teyes units have...

As for the unknown connectors, do you have the wiring diagram for your model year? I would highly suggest finding the PDF or getting a hard copy, usually from ebay. You'll find it very helpful, and it should with a little reading tell you what those connectors are for. If the system was working fine before, I would NOT connect them. You could short something. FYI I believe the computer behind the glovebox is the engine ECU.
