Upon further reflection. You could remove the cable/wires from the cradle as per the youtube video I cited above and wire the GPS from below, i.e. from under the tupperware, going up to the GPS cradle. After plugging everything in down below, you could plug in the two wire looms in the Cradle, reassemble the cradle, and get by with a much smaller hole.
Upon further reflection, I think that's what I should have done.
1. Remove cradle and disassemble as per the video
2. Push(Carefully!) wiring down under the dash through the hole it came up through
3. Route the wire to where you want it to end up, e.g. in my case, in the speaker area (probably need a stiff wire and tape to help feed the GPS wiring and remember to protect the two plugs which you detached from the cradle)
4. Drill a hole in the grille, feed the wire upward
5. Reassemble the cradle and mount in its new location.
Totally confusing? No? Let me try it again! Maybe you could PM me and can exchange phone numbers and talk it through??
