Ok.. here is where my project stands:
there are two obvious choices here, midori and windows. i prefer to go the midori way, but since i am planning to mount the ia-1 upside down and linux cannot rotate the display, it is out of the question. Windows on the other hand has software to do this (Pivot), but since i dont have a microdrive to install it on (only a USB drive), this will require some $$ investment, which i rather avoid. the added bonus w/ windows is that installing gps software will be a breeze.
As an aside, i should mention that i did try to physicaly flip the lcd inside the case in verious creative ways, to no success. the data cord is just a bit too short (maybe 1 cm). i did discover that the whole monitor unit can be mounted backwards if you use spacers and longer screws. but that doesnt help me much, maybe it helps you.
* Power Supply:
gave up on manufacturing a voltage regulator from the car's 12v-dc by myself, mainly because the ia-1
requires four different voltages, and i am too lazy to do that, i will just get an invertor from rat shack.
* Physical fit:
I have designed a realy nice bracket to mount the ia-1 in my car, will post pictures during spring break (2 weeks from now)
