Ask for a re-deal.

If your M1A2 SEP still has any of the older Army embedded GPS receiver (AEGR) circuit cards, NSN 5998-01-463-1005 (PN 12438580 or 110100), don't play the hand you were dealt.

Any older AEGR cards found in the turret mission processing unit (TMPU) and the improved launch electronics control unit (ILECU) during repair should be turned in now! Those cards need to be upgraded to the new version, NSN 5998-01-496-5901 (PN 12438580-2).

Not sure which cards are in your vehicle? Here's how to check your M1A2 SEP with software version 4.0.

1. Make sure the tank's MASTER POWER and TURRET POWER are on.

2. Press the DIAG push button on the Commander's display unit (CDU) to enter the diagnostic menu.

3. Press the STATUS pushbutton to enter the status menu.

4. Press the SW STATUS pushbutton to enter the software status menu. If the screen shows an AEGR software version of 2.2.2 or below, you need a replacement AEGR card.

Turn in unserviceable cards following your regular turn-in procedures. Your TACOM LAR can help.
