I am wondering, does the FMC at some point prior to landing tunes in the ILS from the pref init page? or I need to do it manually?

"...does the FMC at some point prior to landing tunes in the ILS from the pref init page?"Unfortunately, aircraft like 737NG's and 767-200/300's require manual tuning, Moshe. At least on the 767, you can tune all three ILS receivers at once, but on the 737, you have to tune the two NAV radio panels independently. There is no NAV RAD FMC page on these aircraft.The FMC, however, can use the ILS frequency, you dial in, to update it's position.Cheers.Ian.

I seem to recall that the DF737 (a -400) would automatically tune the NAV radios, or am I mistaken about this (maybe I'm thinking of the PSS A320). Anyway, assuming my memory isn't faulty, do real 737-400's have the ability to automatically tune NAV radios and why has this feature been left out of real 737NGs? Just curious.

"I seem to recall that the DF737 (a -400) would automatically tune the NAV radios, or am I mistaken about this (maybe I'm thinking of the PSS A320)."It may depend on what you mean by "NAV radios", Craig. I did hear that the VOR's (at least) were tuned automatically on some -400's. Not so on the NG's. Can't tell you why tho'. DME's on the other hand are definitely tuned by the FMC's on the NG. I don't know if ILS's were ever autotuned by the FMC's on 737's.The NG usually has GPS, so perhaps VOR's (for position fixing) are redundant in this case? VORs have always been the least accurate way of updating position (They can't be used alone and must be used in conjuction with DME as in a "VD" (VOR-DME) fix). DME-DME is a better solution... except, of course, where there is only one DME available... or where the second DME is not providing very good geometry for a fix.Hope this helps.Cheers.Ian.
