2009 LaCrosse: Radio & Odometer Problems ?

[Robert11]

Hello,
Terrific Forum.

Have a new 2009 LaCrosse CXL

A few annoyances.

The radio keeps leaving the Preset Number that I push.
Plays just fine for about 15-20 minutes, then jumps.
Always happens, wherever I am.

It's almost as if it seems the SEEK was pushed.
Seek is on radio, not steering wheel.

Doesn't jump to another Preset; jumps to the next station it happens to find.

Any TSB or thoughts on this ?

Is there a sensitivity adj. somewhere, or probably just a defective radio ?
Flaky ground, somewhere ?

Can't reset the A or B Odometers to 0 when driving by pushing the Set/Reset arrow. Any thoughts ?

Thanks,
Bob
