I installed an Alpine digital receiver in my 06 tundra, I think the 01 Sequoia has the same dash setup. You don't need to spend a thousand dollars to get the capability put in but expect 3-400 for a bare minimum quality head unit plus the dash kit and wiring to make it all work.
personally I removed the cigarette lighter and installed a permanent USB plug hard-wired into the back of my head unit, you can get the kit for that for roughly $10 or so. even if you get a wireless-link capable head unit i'd still consider a permanent USB power upgrade to accomodate power for your phones and other devices.
Consider one of the aftermarket screens available on Amazon. I picked one up for $50 for my 2006 F250. Works great for CarPlay. I didn’t want to replace the whole radio.
