Car PC on the cheap
cheap older laptop with decent mhz = $300, more than likely already has OS
GPS USB $40
AC/DC Inverter $50
USB Sound Card $40
Extra Wires, Cabling $30
$610 then for something that does most of what everyone wants. Sure you can build a via system for around the same price but a laptop would be easier when dealing with power issues. You can ad or take away $100 o so and still be decent.
But no software is included in that.
My system on the other hand will be using a laptop. but The Screen Fabrication alone cost me $100, the screen was under 200, but i'll be spending good money on getting the sound integrated with my setup nicely.
When Im done I expect to have paid $1500-2000 total. Still have alot of stuff to get.
Good USB Sound = $200
Sound Processor/Crossover/EQ ($700?)
Wiring/Power/Extra Fluff $150
Custom Fab Work for mounting everything $100
