Just get a CarPlay screen. That’s what I’ve been using.I have been following since February and very interested in purchasing for my 03 LC. The simplest knobs for HVAC control makes the most sense to me. After years of using my phone for music, navigations, and calls, I don't want to install a head unit. Is there a way to avoid a head unit completely and just use bluetooth for either Android or Apple phone connection for connecting to the speakers?
Are you getting Toyota to fab your PCBs?V1:
- Bare bones, Toyota-level reliability
This is great! I’ll take one!Progress Update
Core hardware direction is now locked and we’re transitioning into schematic and PCB.
v1 uses a dual rotary setup for TEMP and FAN (with push-off on fan), supported by dedicated physical buttons for AUTO, A/C, RECIRC, MODE, and FRONT DEFROST. MODE cycles through vent positions with indicator feedback.
Feedback is kept simple and OEM-focused: a small center display for temperature only, mode indicators (Face / Bi-level / Floor / Defrost), a fan level LED bar, and active-state indication on key functions.
System behavior is designed to mirror factory AUTO climate operation, with proper integration into OEM dash illumination for dimming.
