Just wanted some input from owners:

1) Do you find you use your unit enough to warrant the purchase?
2) Do you use it in the LM?
3) Besides the maps/directions, do they serve any other purposes features?

From what I figured, the 250 is the entry level. So what features are worth springing the extra $$ for?

Does the fm transmitter feature allow me to use my car audio at the same time? Or does the voice of the GPS require for me to set my audio to the fm frequency therefore no car audio?

And I don't see any benefit of the bluetooth feature or mp3
