Ended up installing a retail model identical to the "official" Lexus option here in Japan (and about 40% cheaper at that!). It's DREC-4000 by Eclipse.
Unfortunately, found no exact model on the US Amazon store, but you could probably import from Japan if you'd like…*or maybe it goes under a different model name in the US.

I also searched high and low, and even bought one… ( http://goo.gl/6o2oOt ) This one is pretty good tech-wise, but I never installed it after trying it out. Just WAY too huge, especially annoying for the front passenger.

The DREC 4000 is not very good sensor-wise. Only 720p (1Mpix resolution)…*but because it's a separate type, it is really small. Just the camera, with built-in GPS module goes on the front glass, the small microphone thingy goes on dashboard, and the recorded itself goes inside the glove box.

The recorder supports HDR recording, and records in MP4 format, which is directly readable by Lexus navigation (just put recorder's SD inside micro-SD slot of the navi). Image quality is not extremely good, but not too bad either. You can try to search vids on youtube, just enter the model number.
So well… I can't tell I'm extremely satisfied, but that's the best I found that fits my needs to a decent degree. Hope there's an upgraded model coming out soon…

Here's the link on Amazon JP:

Love how it shows which tire now. Do not forget to check that spare tire, I keep it a little over inflated.

Enjoy!:)

Did you guys know there is a mini storage compartment on the left hand side of steering wheel under the buttons? Just press the button and it pops open. Maybe other lexus models have this but I havent driven a lexus in a while!

Just saw that today...I feel so stoked

Yes, this is an AWESOME storage compartment. It's actually really nicely sized, and it has a cool button with a soft open that gives it that luxury finish feel. I keep a change pouch and some keys that I almost never use in there.

There's also a little side bin thing on the left of the passenger seat, both door side pockets expand, with a cupholder of sorts in each.

Yep, holds my calling cards and a spare pen.

Comes in very handy. :)

This might go without saying...

In the f-sport, the odometer reading was turned off when I picked up the car. Took me a while to figure out that pressing the "ODO/Trip" button will display the odometer and trip meters on the center tachometer. Looks better with it switched off, giving it a much cleaner look

Didn't the mid 1960s Ford Thunderbird have that as a signature feature?

Yes, the t-bird did that, and the current model mustangs are doing it too...

I disagree the 8 speed in my LS is sensational and was the first they did in 07 .

Yes, I agree. I have a 2012 ISF with the 8 speed transmission and its quite amazing. I am still amazed how well the transmission performs. I also had the 2013 f-sport RX350 with the first time 8 speed transmission, and it drove much smoother than the 6 speed equivalent.

I have no complaints about the 8 speed tranny but do not like how it is programmed to stay at such low RPM when driving conservatively. Need a setting somewhere between normal and sport.

Yes!!
 

My AC makes a "water" sound, but only when the AC is on.....I am currently fighting with the dealer who wants to say it's "normal". It's driving me nuts!!

I'm so glad to know I'm not crazy. I've been fight with my dealer about this "gurgling" noise for over a month now. Matter of fact I have a meeting with the GM and the regional FTS from Chicago today. Has anyone else actually complained, and what resolution did you get?

Are you going to have them take a ride with you? Maybe you can get some petition going and I'll gladly sign!

I had the service supervisor "hear" it. Then they put me off until the regional FTS could come to town and "hear" it. At which time he stated it was "normal" and nothing would be done. I then called Lexus NA and the General Manager of the dealership. They are bringing the FTS back today to ride with me and the GM. I don't expect they will give me any answer other than it's "normal". I tried explaining that if it were normal then every other car I've ever driven and they sell would make the same noise. Sadly, I believe this will be a no win situation for me. Only hoping as more of these roll out and the need for AC becomes necessary with summer that more complaints will arise as people from the cold weather states begin hearing it.
