Cost to install IFR GPS in a basic IFR 172?

The requirement for a current database, if any, comes from the Approved Flight
Manual Supplement. Not all AFMSs have this requirement, but most do. You have to
read the AFMS for -that- airplane. Many UPS GX50/60 installs used boiler-plate
AFMS verbage that does not include the requirement for a current database.
Instead it requires only that the PIC determines that the procedure in the
database matches the procedure as currently published, or something like that.

True. The AFMS for my 430 installation does require a current DB and I
had forgotten that not all were that way.

My comment was more to the fact that the database has to be current for
the approach (i.e. the approach or waypoint must be in the database). As
I mentioned earlier, I'm currently visting outside of my normal database
coverage area. As I don't have the northern Michigan approaches in the
database, I can't do a GPS approach. Nor can I do any approach that
utilizes a NDB. Kinda limits my options.

Its the first time in the two years of flying behind the 430 that wish I
had kept my working ADF.
