    3) Radiomodule ordered price 148,25 incl Shipping and antennacable
    The well known module on this Forum I guess....
    USB controlled radio module

    works with met RR en CTF and more?

    4)OBD usb interface ordered price: 19,26 incl shipping

    I will connect this interface to the OBD2-system parallel to the factoryconnector on the dash. This way VW-shop can still acces my car through the original connector on the dash.
    IF I can get OBD functionality in RR or CTF, nice, if not not too bad, the main idea is allway having your diagnostic equipement with you... (I use VAGcom for my VW-diagnostics)

    Found at home in the "not using anymore-corner":

    ASUS TUSL2-C rev.1.04 Motherboard, with mounted on that, (if I remember correctly) a Intel P3 processor.

    256MB PC133 memmorycard

    ASUS V7100PRO/T/P/32M/SD/U videocard

    Creative Labs CT4810 soundcard.

    Maxtor Diamondmax plus8 40GB harddisk 3,5"

    Yet to buy / get:

    DVD player

    W-LAN-Card (for updates, MP3 uploads form my home-pc (car is on the driveway 5 meters from my PC)


    (small)materials for connecting and finishing the installation.

    software for controll and navigation (maps for europe)

    Perhaps a dashboardpanel for the T4 so it can be restored to original status when it's sold without the carpc.

    Last week the LCD screen, the OBD-interface and the GPS-receiver arrived.... I guess the radio module will arrive early next week....

    Today I had a little time to spare.....

    At home I found an amplifier which I used in one of my previous cars...

    sound form the line out of the soundcard to the line in of the amplifier..........

    4 x 90 watt.... seems enough to me...

    Slightly demolished an old computercasing....

    The striped part is the part I removed to use as a basis for the new casing.
    The blue dots were rivets I drilled out, the green line is the place I smashed the electric jigsaw throug...

    This is the piece I took from the original casing, at the blue dots I mounted it with small screws to an equal-sized piece of plywood. The top of the casing will be screwed to this plywood-bottom.

    Motherboard mounted and sound- and VGA-card installed....

    During the first boot I could look what processor is mounted on this motherboard.
    I remembered correctly: An Intel P3 1,2GHz

    Now we can start with testing the software configuration.....
