Sorry for taking so long to answer your question, It has been a while but no it was not equiped with EGPWS, the only RJ's in the LX fleet with EGPWS are HB-IYX, IYW, IYZ, IYY. Recal a number of 4. There might be one more.
SS I like your explanation. There is also the thing about the APU required to keep the outflow vavle open for pressurisation system.
In short No APU NO GO!
