Just bought a used 15' RX 350. Amazing comfort! I'm okay with no guides but what messes me up is the position of the camera, it's not centered on the back! lol
Why though? The parking sensor and the backup camera are usually enough. When the parking sensor shows 1 bar left for the rear, that tells me I shouldn't back up anymore. And the camera tells me if things are clear in the blindspot of the rear view mirror.
My 2017 Civic had those lines but no parking sensor.
I do not miss those lines as the beep patterns of the parking sensor were more useful than the lines.
All sorts of reason why folks would want the backup lines. To me the more useful are the lines that are connected to the steering, which show the position intended path. I have a curved driveway and I have leaned to position the joint in the driveway on my screen.
I have a 13RX, and I have factory Nav, so my rear view is on the main screen. No lines with this system. The in-mirror version has the lines according to the manual for the 13RX, but I don't have this version. Not having guidelines for the large screen version seems wrong to me.
I use a real low-tech solution: a pair of Utopicar long design mirrors. They glue to the outside mirrors. Position along the bottom edge. They swivel in one direction and I rotate them down (not even all the way) so as I pull into a parking slip, in either direction, I can see the ground beside the car including the lines and the cars beside me. As with anything it takes a few trials to accurately interpret what the mirrors show. Works pretty well. On road trips I can rotate them up. They don't extend the close-in view width much but do extend the further back view width so on roads with 3-4 lanes you can get a quick glimpse of the traffic load behind. They cost $10 or so.
About a year ago my wife purchased a very nice 2013 RX350 with 40,000 mi on it, but because she spends most of the year with the grandkids, she never really studied the features of the car, so we now have some questions about the rear backup camera system.
Looking in the Owner's Manual (8 Pages 320-328), it first talks about a rear view mirror camera that comes on when in reverse gear, and shows the video on the left side of the mirror. It contains depicted lines in contrasting colors to show whenever the car will be based on th esteering angle to help the driver "project" their path. Her car apparently does not HAVE that system on it, because it does not even have the type Power Button used to turn the rear camera system on and off (it has only a "!" and a ")" to turn the auto dimming feature off.
The manual then talks about the system on cars with an audio system that uses the center navigation display to show a picture of behind the car. (3 Pages 329-332) Great, it's BIGGER, but the driver has to look DOWN and not out of the windows as is natural with a rear view mirror.
But what confuses me is that the more expensive option shown NO projected path lines showing where the car is actually going in reverse, so it's up to the driver to guesstimate where the car will go depending upon how the steering wheel is turned.
I have driven a lot of Post-2008 vehicles (on which rear TV cameras are mandated), and even the LOWEST cost cars have predicted path lines that move with steering wheel to show rearwars progress.
I am sure something is malfunctioning, or we are using it wrong, because it seems unlikely Lexus would supply an inferior system where one has to be heads-down, and guess the path of the car. I know the car is nearly 10 years old, and is ancient by technological standards, but surely it has as good a system as the 2010 Kia I recently drove?
Personally, I don't LIKE such bells and whistles, so when the dealer offered my wife $3200 for her mint nearly showroom 2003 RX300 with 55,000 miles she had owned for 15 years, I sold my then present car and bought her 2003 RX from her so she could justify the 2013 one, and it of course has NO gadgets, which is perfectly fine with me.
But in case I read the owner's manual wrong, I would like to ask those more familiar with their 3rd RXs than my wife and me to explain how to get the screen to better show a projected rearward path.
