Hey, long time...

Does the FM antenna plug into the back of the head unit for ML, or is it different?

Ok, I have no clue what's in the new generation IS for speakers. What's in there from the factory (non-fancy upgraded bullshit stereo please)... and what are they capable of taking?

I'd imagine that IS350s are great candidates for kickpanel installs cause they're all freaking autos. Can the doors take 8" midbasses??? That would be cool...

I honestly, haven't seen a whole lot of custom work in new IS'. So I don't know what they can take... I'd love to learn more so I can help people out around here.

Here are a few IS350 installs that I have found online (all are by simplicityinsound... San Jose, California):

ICIXSound.COM Forums - Install Log of my most involved install in a long time - Please DONT reply to this
Just got my system done...PICS!!!!! - Club Lexus Forums
IS350 Stealth audio install...thought i'd share some pics - Club Lexus Forums <------ AWESOME

Simplicity In Sound for the installer. The guy's name is Bing... he's insane.

Has anyone sucessfully installed a remote start on a new IS250 or 350?

i have been inquiring bout getting a remote start for awhile and so far for the is x50 guys there is nothing that is specific like an i-data part that will make it work yet. we spoke to a rep at the company today and they said that they have a part in the works and should be out by spring to summer time. they said there are ways to make it work now without the data part bt it will require you to cut wires they said there are some behind the glovebox bt recommeded that a person wait for the bypass parts to come out so no cutting will be required

Remote turn on

I found that the remote wire on my car was actually red. I have read a lot of people saying that it was pink or orange. I found a red on on the harness farthest to the back that was only hot when ignition was on, and everything is working perfect when i tapped into that one. Hope that helps!!

@ngerasimato I have successfully installed one. If you dont have experence i wouldnt try it yourself.

@lisnup65 I was not able to find the negative park light wire as you have listed. References a 28 pin plug that i have for the life of me not able to find. The car has two positive light wires and i dont wanna run that because i dont wanna have to run a relay. could you describe exactly where it is or provide a pic or diagram. My description has it facing the firewall hoever i dont see anything on the side or the back of the fuse box.
