    i mean if the ground of the amplifier; check also to use short and soldered cables;
    if the cable is too cheap, may be a shielding broblem

    little delay due to non working internet connection :-\
    I've almost done Step 2 (audio setup)!

    I found an old (but unused) 4x50W audio amplifier, I need only two channel but I found only that model. But it's ok, I will use only two channel. (30 eur)

    I bought on ebay this ground loop isolator to clear audio signal (16 eur)

    and a quality audio cable (7 eur)

    installed everything in a test configuration and it's ok... I have some other audio noise but I still waiting for a power supply filter (found on ebay) to solve eliminate the last noise.
    I use both permanent and switched +12v for powering the amplifier, so it turns on when car is on (actually it turns on when the key is in 'on' position, even with car off).
    I placed the amplifier at passenger's feet, with a small wood plate covered with decorative adhesive plastic. The passenger's mat will cover almost all the amplifier and it will not be visible.

    Good job, it seems pretty nice. I want to see more photos of the tablet in position, and also while removing and putting it back(and a video wouldn't be bad either). I will soon try to make something similar at a friend's 147 fl.

    Only thing that might worry me is where you placed the amplifier. Your pollen filter is located behind that area, right(at least in 147 it is and I doubt it's any different in the GT)? That one time a year that you will want to replace it it might be a bit tricky. And I'm telling you this because it was a bit tricky for me, and all I have behind the carpet there is just LOTS of wires.

    Great progress on the install. I would however advise that you find better placement for that amp. Having 12V power running below someone's feet is a bit risky, not to mention water (is they come in with wet shoes etc.) coming in contact with the amp (both audio and power contections).

    you're right for the water issue! However both the amp and its install is 'temporary' to let other step progress. At the end of all I'll see to find a better placement

    Ciao! Here we are at STEP 3: INSTALLING THE DOCK

    This is a complex part too, since I can't half-open the dash as per shiltz' install. The Alfa Romeo dash is a single piece and I cannot mount hinges and locks from the back, so I should find a way to install the dock from the front, and also mantain access to interior of the dash for maintenance and service.

    Main goal is to keep the side plastic tabs of the 2-din space, to be able to revert to stock in the future.

    First of all, I realized a support for the magnetic lock:

    remember to always use protections!

    the lock is in place and firmly screwed. Note the black adhesive tape, I used it make this part less visible after the complete install..

    Now the trickiest part: mount the hinge on the dock and the dock in the dash.

    after buying a variety of hinges..

    I found the perfect material:

    yes, it's pvc floor
    I use a piece of this pvc floor as hinge because it is flexible and robust, and give me the ability to modify as I want

    I block it firmly with cable ties and the always useful super glue

    and then glued with a metallic support, that I made before with the right holes

    on the other end I glued the correspondant part for the magnetic lock

    all cables connected!
    Here you can see another piece of the magic pvc floor used to cover the bottom part of the 2-din space

    again, the dock is not as ugly as appears in these pics, my camera flash highlights every small imperfections

    didn't remember if I already said, but the adhesive tape at the bottom of the dock has the important function of protect the tab from scratch

    and finally, here it is with the galaxy tab inserted!

    there is enough space to insert fingers..

    but if you need, or for better pull the tab, you can detach the dock from the magnetic lock

    I need to install it off-center. This is needed for avoiding cutting the side plastic tabs. However it's not bad to have it closer to the driver

    in this side view you can see the alignment with the dash. I can't put it deeply in the dash because of the structure of the 2-din space and for leave enough space for the magnetic lock to push-to-unlock (about 2mm)

    here you can see clearly the pvc hinge glued to the metallic support, and then screwed at the plastic tab. when I need to access the inside of the dash, I simply unscrew these screw and detach the dock from the magnetic lock

    now I have to cover this space.. I will use the 2-din frame I bought for the old JVC car system

    I can use only the right part because all other sides (left, top and bottom) have no enough space to fit anything!
