Having successfully installed NAV-TV, my attention has now turned to the use of the AV "aux. input" afforded by the installation. Thus, turning to channel "AV" allows the use of a single RCA video and audio input. One such application is the installation of a real Windows PC into the M5. Here are my ideas.
The benefits of a real PC in the car are extensive - some while in motion and some while stationary. The applications I envision are MP3 audio playback, DVD video playback, full MS Office support, including Word, Excel, Powerpoint, etc., and most importantly, wireless web surfing (for, i.e., Doppler radar, weather forecasts, access to bmwm5.com) and e-mail.
While a variety of solutions and installation options are possible, here is my idea. I envision a modified laptop - either with or without a docking station installed in the vehicle, probably via a custon bracket at the top of the trunk or near the NAV-TV unit, CD player, etc.
For video: My IBM has s-vid out built into the laptop. A simple s-vid to composite video converter would allow me to convert the s-vid output to composite video, and then feed the composite video into the NAV-TV "AV" input for display on the NAV screen.
For Audio: Simple audio out of the IBM and wired into the RCA Audio in on the NAV-TV "AV" input.
For Power: Should be easy to tap a line from the NAV-TV, CD Components to a DC adaptor to power the PC.
For Wireless: There is a small antenna on the PCMCIA card that operates my wireless internet connection via Verizon. That 'should' suffice by simply extending that antenna in the trunk. If necessary, I will look at the cellular phone antenna installation for the BMW cell phones, and modify that antenna feed into the PCMCIA card. (thoughts?? It's prewired in the M5 - right??)
Now the hard part:
Mouse: I am thinking a touchpad to be installed on the center console where the small storage compartment is located. I am thinking about removing the door that slides up and down, then custom installing a touchpad at that location that pivots up and down. This provides simple unobtrusive mouse operation while your arm is on the center console. A black touchpad would look great at that location, also. (how hard would it be to fish a wire from that location to the trunk??)
Keyboard: I am thinking about a wireless RF keyboard. Store it in the trunk when not in use, because for simple web surfing, e-mail retireval, etc. it is not really needed. Ideas welcome here.
The final circuit needed will be an automatic boot-up and shut down from a 'standby' state tied to 'something'. I notice that, on the NAV DVD player, it seems to boot up whenever a door or the trunk is opened, and then is goes to sleep if there is no activity 5 minutes later. I suppose the intent is to boot up the NAV system in anticipation of use. This can be tied to the PC, i.e., have it standby and then turn on for quick access, either through a lan card or hardwiring the power switch.
Anyway... some food for thought. This does not seem as hard as it looks - I like the mouse location, I like the wireless option, and it would certainly be pretty neat to see a fully functional Windows desktop on demand.
Thoughts?

p.s. I know at least one participant here has used some sort of mini-pc for this purpose. But, as I understand it, there is no PCMCIA slot on that devise for the wireless card.
