I?m working on marketing an in car computing solution to four separate
market segments.  I need to know first, if there are any other similar
products and how much they are?  Second, I need to know how many
working parents (soccer moms) there are, business executives, Car
Audio enthusiasts and Car performance enthusiasts / customizers in the
US to find out the total market size.  And lastly what percentage of
each of the four segments would be likely to buy this type of product?
	The market size data is the most important information.  I need
numbers and references for the data.

	These are several solutions that I have found out there.  These are
some of the links to similar products.  It is software based.
