MetroGuide any good?

Does anyone use MetroGuide?

I have an eTrex Legend and travel interstate a fir bit. I know it isn't turn by turn, but do you find it useful to key in an address and say "Goto" and then it sort of guides you in?

OziExplorer's fine for the tracks, but you can't look up a street address in it and I don't have maps to street detail anyway.

I have a VDO Dayton Nav system in the Rodeo which is awesome IF I have the car with me, but for example am going to Perth and need to visit about 8 clients and have never been there before.

And before you ask, Budget don't have hire cars with Nav systems in them in Perth. I've checked.

Would like some feedback before shelling out $175 worth of coin.

Cheers,

Smocky.
