Is250 head unit
Hi guys this is my first post here. I just bought an 08 is250 because I got a new job that requires some driving. I got the non nav non ml sound system but really need Bluetooth, and nav would be nice as well. After a lot of studying I bought the pioneer avic-7100nex head unit.
Mounting the unit will not be a problem for me as I've been a body man/fabricator for 18 years. It will be mounted right below the oem radio display after I relocate the hazard switch panel.
My problem, if any, will be the wiring. I have the metra tyto-01 to retain the oem amp. It says it works with the 2nd gen is cars but as much as I search these forums and others like them, I can't find anyone with an aftermarket head unit that mention using the metra harness on a 2nd gen.
Sorry for the long post but long story short I'm wondering if anyone knows if the metra tyto-01 will be plug and play on an is250. Thanks for any help you can give as I'd like to install next weekend.

Hey thanks for the reply! I noticed that it was all first gen cars using that harness after I ordered it. The harness has the 2nd Gen listed as a car that it works with but I feel like it's not going to be plug and play. I have the wiring diagram for the car so I'm just gonna splice it in and see what happens. If it doesn't work I'll bite the bullet and let a pro wire it after I mount the unit like I want it.

i think i figured it out. I have the head unit working along with ac controls using factory amp and speakers. Im going to test it out for a few days to make sure i haven't lost any functionality and ill post about how i did it. It is actually so simple its ridiculous that its so hard to find info on how to do it. hopefully everything is as perfect as it seems to be so i can get this info out there for anyone else trying to do it.

I so wish someone close to me knew how to do this.. I would pay whatever I needed to get a touchscreen headunit installed lol.
Personally, I would start from scratch if I did this.. simply wire up aftermarket amps and speakers, bypass the factory equipment.

Honestly I was about to sell the radio and dash panel to whoever would give me what I had in the radio alone if they would trade me their factory stuff as well. I'm glad I figured this out first because I have about 20 hours in the dash kit.

First off I have to commend you for your work and your skills on fabricating the radio mount and trim. Here's a link to what others have done. The biggest problem has been relocating some items which have been put behind or in the glove box. If you figured it out, then you are ahead! nice Job. You can see pics here throughout the pages. https://www.clublexus.com/forums/is-...our-setup.html

I've been driving the car a while now and just wanted to report that as far as I can tell everything is working. Radio sounds good with factory speakers and amp and all accessories are functional including ac controls.
The only thing I did was removed all the wires from the oem 20 pin connector that would hook into the metra tyto-01 connector except the power ground acc and illumination. I wired those wires straight to the tyto-01 and hooked the rest back into the oem head unit board. I guess the 20 pin to the oem head unit only has to provide power to keep the ac controls functional.
I also modified the 12 volt cig lighter type plug to accept 2 usb extensions and the factory aux plug to accept the aux extension that came with the head unit so everything looks factory.
I did have to locate the vss and reverse wires in the factory harness to make sure I had full functionality. No pics but I can help anyone that needs to find them. I am very happy with this install and I think it will be a pleasure to drive now.

ive been search for days and the information regarding upgrading a second gen IS factory HeadUnit is really fragmented. Maybe when I finally do my install I’ll do a write up or a YouTube be video for the other people who have factory navigation and they’d like to avoid paying $400 to best sonic for the all inclusive overpriced kit.
