I'm pretty sure that the terrain radar isn't included in the 757 III for FSX/SE/P3Dv3 (32bit version),  it's only in the 757 III for P3Dv4 (64bit version).

Hi Mark:
Thank you for the response. That news is really disappointing though.  It can't be that complicated. Just bout every complex aircraft I own has this feature. And my weather radar works ok. Also the TERRAIN callout appears in the HSI.
Strange.
Best regards,
Rick
Update: I was reading the manual and found for sure it is not included in the 32 bit versions.
