I've been trying to find a way to change the pictures of both screens when the car is turned on. Anyone know how to do that?
I have only been able to change the clock wallpaper.

 

not possible ,unless someone comes with a way to hack the navi system like they did on 3rd gen TL

 

Darn.
Oh well, not a big deal then. Thanks.

 

I agree that it would be cool to be able to fully customize the displays and I've even asked if we could change the "Driver1" and "Driver2" to more user defined names, but it would be a lot to expect since car manufacturers don't like to give us that much wiggle room. Maybe someone will figure out how to "jailbreak" the system and allow us some of these things without sacrificing the critical items.

 

This news release about the TLX describes it as having a "customizable welcome screen"... so it must be possible!

 

oops. Sorry. Here's the link
2015 Acura TLX: Interior - Honda.com

 

I re-read that press release and the only instances I found with the word "custom" or it's variant were as follows:

MID information categories, depending on vehicle grade, include:

Vehicle Settings customization
Digital odometer and dual digital trip meters
Outside temperature
Shift lever position
Elapsed time
Average speed
Average fuel economy
Instant fuel economy
Estimated remaining fuel range
Maintenance Minder™
Tire pressure monitoring system (TPMS)
Engine oil life
Lane Keeping Assist System (LKAS)
Turn-by-turn navigation (with Technology or Advance Package)
Road Departure Mitigation (RDM)
Collision Mitigation Braking System™ (CMBS™) with head-up warning
Adaptive Cruise Control (ACC) with Low-Speed Follow
Audio/Information Screen
All TLX models feature a bright, full-color 8-inch audio/information screen positioned high in the center stack of the instrument panel. Its high placement puts it close to the driver's line of sight where it's easy to see. Besides audio system information, the screen also offers backup camera views when in reverse and access to a range of customizable features.

On-Demand Multi-Use Display™
As in the RLX and MDX, a 7-inch On Demand Multi-Use Display™ (ODMD) touch screen is positioned within easy reach of the driver and front passenger. The touchscreen controls a wide range of features, and with its contextual menus, displays relevant items while minimizing clutter. To simplify use, the screen offers audible and vibratory touch (haptic) feedback — both can be adjusted or shut off based on the owner's preference. Customizable shortcuts allow the TLX driver to set easy-to-access presets for Places, Phone, Climate and Audio functional categories.

I may have missed it, but I've looked through the Owner's manual and tried all the menus, and I haven't found a way yet. I'm sure if there is a way, someone will find it and post it.
