Hey guys,

I got my hands on an OEM replica nav unit from my sisters IS350. It was installed by the PO. Below are pics of all the connectors that came with it. My question is what aftermarket connectors will I need to make it work with my Non-nav IS250. The last 3 pics are confusing the hell out of me. It looks like the PO tapped into 12V power for some sort of external unit? IDK. Any help is appreciated!








This is where the 12V tap comes in.

It then goes to this for fuse protection?

The 3 connectors at the end of the tap.

 

It should just be plug and play. You can ground the brake wire if you want to watch movie while driving.

 

^^^^Yep, we all should watch movies while driving - to heck with looking at the road

I hope youre right that its plug n play. Would make my life much easier.

 

If anything I'll ground the brake signal so I can use the nav while driving. Might not even use the nav as the map is outaded and i dont wanna pay Lexus to update it.

 

What year is your IS250

 

The radio in your picture is for 2010-2013

 

2006. So it wont be plug n play i guess. I havent had a chance to look yet but i will tomorrow

 

the top unit is plug and play. the radio is not, you could use your stock radio

 

Took the radio out and found part number. Turns out this is a FlyAudio head unit. Seems to be plug n play. Dope.

 

Got it installed. GPS isn't working but I wasn't planning on using it anyway. Everything else is working fine (that is wired up). Even found away to keep my existing A2DP bluetooth to stream audio with my phone.

Now I'm trying to change the boot logo but I'm unable to access the boot menu by holding down on the center of the screen during boot up. It just says to calibrate the screen. No green screen like in the thread below. Any ideas?

From the pictures, it looks like your unit is different than the one in the link. You probably need to do something different.

 

Yeah I found out later on those instructions are for the RoadRover NAV Unit. Figured it out tho.
