    woo hoo, even better news!

    so i downloaded drivers for all the major manufactures (globasat, holux, ambicom, and more) and everyone i could find but 2 use the same Prolific serial-to-virtual-com-port drivers. only one of the 2 that didn't was for sale in the US at all, so i got it, installed drivers, plugged her in and no more blue screen with google earth! and no dropping of connection to it with streets & trips either.

    it's the 66 channel QStarx Q818X. it's actually a bluetooth unit but has a tethered usb option too. unfortunately, it's not sealed so it's going to have to go inside the jeep. however, i consistently get 10 or 11 satelites inside my apartment with it, whereas with the globalsat i only got 8 - so mounting it inside might be about the same as mounting the globalsat outside.

    it uses the MTK chipset instead of the more common SirF III... lots of neat features, but overall i'm just happy to have something that works with my laptop!

    so i'm back finally workin on this project again... here are the updates:

    - newer version of google earth and i've started using XPort, not sure which fixed it, but earth no longer crashes with the globalsat gps

    - this weekend mounted the HP Quickdock and ran cables, forgot to take pictures of the mount, but will do when i finish some wiring.

    - worked on cradle for the HP laptop:













    it works well, you pull the dock cable out a bit and connect the laptop, slide the laptop down into the foam, and then use the little velcro strap to lock it down.... the velcro is just an extra measure for crazy offroading, the foam actually holds it very tight. i used a $5 camping sleeping mat from walmart for the foam.

    - changed rear cig lighter that is powering the laptop/dock/screen to be only on with vehicle, was always on. also wired this off my "accessory override" switch... basically i have every accessory (GPS, iPOD, CB, Laptop/Dock/Screen, and oneday HAM and Cameras) all pulling from power that is only on with the vehicle, but i have one button that overrides that and leaves them on all the time. this is good for offroad trips where you stop lots of times to see stuff, take pics, eat lunch, etc... i can leave the override switch on in those cases and everything doesn't get reset every time i stop... but the rest of the time things will turn of automatically.

    - also wired a momentary switch for the laptop power (will worry about an automatic turn on later, and it will turn off when DC power dissapears just by using windows shutdown rules) and re-did my front switch panel to have more switches in anticipation of some unrelated accessories.

    made an aluminum bracket that attaches between ram mount and screen and hangs down to put keyboard on. using industrial velcro to attach keyboard to bracket





    can still reach all controls on the radio, which really doesn't matter anyway since i usually use the factory steering wheel controls. can't access cd slot or see clock unless move screen higher, but i never use the cd anyway, nor radio much, mainly just use the deck to control the ipod.

    Nice to see another cherokee getting a make over inside I also thought about that type of mount on the dash as well so I could keep the radio but decided to consider a dab supported usb add on and continued with the dash fit of the 10" screen which fits almost perfectly as you have seen in my project.

    What I want to do to my jeep is what you have in the first picture You never know when you need to drive over that pesky car that blocked me in!!!

    I see we wlso went for the obvious CD box out the back installation area. Makes sense I think.

    I had loads of problems initially with the Infinity Amp and the PC could get no sound ever so I went out with my friend and got the Amp to make it all work, shame it did not fit under the seat tho, it was about 1cm too big

    Good stuff.

    I wonder if you are going to have issues with the hard drive when you go offroading...

    i'm going to just wait and see, i won't be surprised at all if it dies and i have to replace with a SSD. but of course, i've had an old ipod bouncing around in offroad vehicles for years now and it hasn't died yet!

    i like what you are doing, right now my carputer is an addition to the existing deck/ipod/amp/speakers, not a replacement... mainly just for navigation, service manuals, and eventually to tie into HAM radio too. however, if i ever get it up and running and all the bugs worked out, i may switch it to be the full entertainment replacement, in which case i'll copy your monitor install

    thanks. with the radio antenna, cb antenna, and soon HAM antenna, it looks like it from the outside too! i'm referring to the dash as my "comm center" from now on

    but yeah, it's way more "practical" than "stylish"

    better than this though:

    here are the pics of the backbone of the system, the HP Quickdock and all the cables.. though I am having trouble with some devices being plugged into the quickdock right now, not yet sure if is hardware or driver problem. ugh.


    so it's tucked behind the interior panel, right next to the back lift-gate:




    i used some velcro cinch straps that i got at REI to secure it so that it is still easily removable if i need to take the whole system inside to work on it. Fry's electronics also has those straps. i just used sheet-metal screws to fasten the end of the straps to the metal:




    one good thing about the CarTFT monitor is that i was able to get a long breakout cable for it, so i only need to run a single cable to the back for vga/usb touch/usb hub/audio in/rca video 1 & 2/power. the other cables you see here are an active USB extension cable (for OBD II interface), a small gauge speaker wire for the remote on/off switch, and speaker wire providing input to the relay in the rear controlling power to all the computer stuff, only 4 cables:



    eventually there will be another cable running from the quickdock audio output to the amp or headunit as well.
