Installing aftermarket HU in 2001 Lexus is300?

Installing an aftermarket head unit (HU) in a 2001 Lexus IS300 typically involves removing the factory stereo and using a wiring harness adapter to connect the new unit without splicing wires. You'll need to carefully remove the trim panel around the stereo, unscrew the factory unit, and disconnect the wiring. Make sure to use a dash kit to ensure a proper fit, as the new HU may not align perfectly with the original mounting points. Finally, test the functionality before reassembling the trim.
