 I have a D10 upgraded to D10A in my LIVP and find it a great backup
 instrument.  I have flown with reference to this instrument exclusively
 and find it stable and accurate.  I do not have the external Magnetic
 correction but the internal magnetic heading information is close enough
 for a backup instrument.  Mine has been in the aircraft for three years,
 the screen in readable and it has not given me a moment of problems.
 Hope this helps in the decision making.
