Lexus Install - The Monitor

Overview | Glove Box Part 1 | Glove Box Part 2 | Monitor | Final


If you're looking to buy the IS300 Nav housing yourself, then these are the parts you will need:

Factory Housing: (minimal - non-motorized version)
-55443-53020 Cover, Display Door (~$30)
-55682-53010 Right Gear (~$20)
-55681-53010 Left Gear (~$20)
-55683-53020 Bottom Support (~$25)

Needed only for models 2003 and below:
55662-53010 Trim (Air-vent dash tray) (~$60)

If you call a Lexus dealership, they'll charge over $300 for these parts. However, I found someone recommending a guy named Leroy at Nalley Roswell Lexus Parts who will give a nice discount of all nav parts bringing the total to a nice $150. (I expect it's because of all the business he's getting from geeks like us installing computers in their cars.) Anyway, I recommend giving him a call: Leroy (678) 795-2050

As for bolts and screws, you'll need these parts from Home Depot

-Threaded Brass/Metal Rod (thinnest one available) 1 foot
-Machine Screw Nut #6 – 32
-Machine Screw and Nuts #4 – 40 x 3/8”
-Metal Screw #8 x 5/8”


I wanted the best monitor possible, since what's the point of building a carputer if I can't even use it? From what I read on and the like, Xenarc makes the best one. Also, at the time I wasn't sure if I should get it touchscreen or not. In case you're debating the same thing for your install, let me just say...GET IT! I don't know how I would have done anything without a touchscreen. It's a no-brainer really, I'm kind of embarresed I even spent time thinking about it. So I went ahead and bought the Xenarc 700TSV.

My only concern with the Xenarc was whether or not it would fit inside the factory nav housing I bought from Lexus. I read some posts on of people installing Lilliput monitors, but never a Xenarc. And the only way to see if it would fit is by taking apart the monitor, which obviously voids the warranty. Anyway, I was in luck, the monitor JUST BARELY fit into the housing. So I was a happy camper.

Here's a shot of the inside of the Xenarc

And here are some shots of the monitor going into the nav housing:

One problem I ran into while installing it into the housing was how to keep it pressed up tightly against the housing? After all, I will be poking and pushing at it with my fingers. There's also no good place to put tape around the housing in order to strap it down. What I did was stick a pencil up behind it. I was actually able to get it sorta wedged up in between the housing and the back of the monitor. That and some tape (where I was able to put it) has done the job rather nicely.

Another issue I had was how to get the monitor to stay up. After all, the housing was made for the screen to close and open. And since all the weight for the screen is in the front, it's "natural" position is closed. How I solved this issue was by placing some pieces of felt on the side of the housing. This way it holds the screen upright but if I apply a little force, it'll close as well. It took a bit of adjusting to find the perfect placement for the felt so that the screen is at a prime viewing angle, but I got it working and that's what counts. In the future, I do hope to motorize it (someday).

Now the fun part, installing it into the car
