2004-2006 Lexus LS430 SC430 Navigation LCD Touch Screen LTA070B054F

𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗗𝗲𝘁𝗮𝗶𝗹𝘀

Replacement TFT LCD display and touch-screen digitizer for the factory navigation monitor installed in select 2004–2006 Lexus LS430 and SC430 vehicles.

This internal screen package allows the original Lexus navigation display to be repaired without replacing the complete dashboard monitor assembly. It is suitable for an LCD with scratches, cracks, dead pixels, faded colors, surface deterioration or a damaged polarizing layer. The included digitizer can restore touch operation when the original touch panel is worn, cracked or unresponsive.

This is an internal replacement component and requires disassembly of the original navigation monitor.
