I'll just ask this, I have no owners manual. Where can I find out how to set my Driver's position memory seats, how to change my home location in my nav, all the stuff you want to do with a new car? I've searched the forum, but most posts have to do with problems or wanting to do things a different way. I just want to know how to do the basics. I've signed on to the Lexus site and seen the partial owner's manuals, but they don't answer my questions. Where can I go to find detailed instructions on the operation of all the gizmos?
On your door there are buttons for setting all the positions. Just press L1 and set together (at the same time) and I believe your settings will be instilled.
Regarding your NAV, when you are at your home location, turn your NAV system on and push "mark", which will mark your location.
I'm no expert at this, but that's my experience in working with my SC. Hope it helps. B
