Well here is another persons (Input).

Get the Nav. from Honda because when you do there is alot of functions that it allows you to do besides just directions.

I really suggest that you get a hold of a (Owners-Manual) for say a 06 EX Civic and read what the many functions are that the Nav. unit affords you as an option.

I have a 06 HCH W/Nav. coming and have had the Nav. unit on the Accord 6-Speed Coupe and I can tell you it allows you to do alot of different things and way to many to try to list on this post.

Reconsider is my best (Advise) to you.

BTW; I have found over the years you get what you pay for and (NO-MORE)
