Going to be picking up my 2005 Land Cruiser next week and one of the first projects is a stereo upgrade. I've read through quite a few of the threads but just want to confirm I'm thinking about this correctly. My plan is to replace the factory Nav with the Teyes CC3 2k unit. I am going to leave the tape deck in place (will probably eventually pull the CD changer out). My plan is to use a new amplifier and run new wiring to new speakers. I may delete the factory amp. Any reason this won't work?
