Electronics keep resetting when restarting

What is your question?

Every time I restart the car, the clock, radio, blower controls loose settings and return to factory settings (or at least I assume they are factory settings because it is always the same). The clock resets to 1am, the radio turns vol down to zero and looses memory of last station, the CD looses track of last played track, temp resets to Celsius instead of Fahrenheit, auto control temp goes back to 72 (or equivalent celsius temp), etc. I have disconnected the battery for 20 mins with no change. I have disconnected the battery and touched jumped positive lead to ground to drain capacitors, with no change. Also, seat does not go back all the way, but this may be unrelated

How long has your 2007 Jaguar S-Type had this problem?

bought it in this condition, although previous owner replaced battery
