I'm going to get a GPS for my laptop. The software has Voice directions, but the laptop's volume is to low for me to hear using the laptop's speakers while driving. ( Cargo van ).
I seen gismos like, "http://www.walmart.com/catalog/product.do?product_id=4694330" , but I would like something that I can "over_ride/power" so that it will come through the current station in which I am listening too.
Is there an adjustable FM/transmitter or anyway to adjust a prebuilt unit (fm/transmitter)?
