For some reason I am having the following electrical issues in my '01 LS430: -Passenger door does not unlock automatically when handle is pulled -Driver seat moves in only one direction at a time, unlike passenger seat which can recline and move backward -Volume indicator shows only black spaces on any volume -No GPS signal -Music mutes momentarily when volume is too high. -Cigarette lighter doesn't work in front cabin, only in back Are all these issues related? What should be my first steps in troubleshooting this? Thanks.

Can I replace the GPS brain in my 01LS430 with one from maybe an 03 or 04? Alternatively I think I am going to the Street Deck route if this cannot be done. A side note: for some reason I am getting no GPS signal, after i re-calibrate it works for a couple days, then loses the position again? Any ideas?
