  • Nexus 7 (Android) in a 2001 Audi S4

    So about a year ago this stereo died.


    so having no money to replace the original 2000 stereo I rigged up an old audio control 2 way x-over to the rca's that go to the amp (they used to go to the radio) and then just plugged in a 1/8th" to dual rca stereo cable and have just been playing music, podcasts, Pandora, ect from my iphone.




    So I've been looking into replacing the old broken touch screen with what ever other top of the line nav touch-screen the auto industry has to offer ($1300.00-$2000.00) and got to thinking. Hell I'm not even using HD radio, cd or dvd player and the nav sucks! I'm spoiled on internet streaming audio and I miss my android google maps so lets check out these android 7" pads.

    Long story longer, I researched all the current 7" tablets and decided to pre-order the upcoming Google Nexus 7.
    It has the fastest quad cord processor and highest resolution of any 7" pad on the market and it's only $200.00 (8 gig) ans $250.00 (16 gig) It should be in my mail box tomorrow.
    Also while researching I found this website, hence this post.

    So far what I've done:

    Got the exact dimension of the tablet, made a cardboard template and test fitted it in the old opening for the radio.



    Can it be this easy?!?!? I was fully expecting it to involve a lot of ABS, Super glue and bondo , But I might get away with just trimming down the old bezel with the dremel and just snapping it in.

    Here is a picture of the bezel turned around and snapped in over the top of the carboard Nexus 7.




    I have also ordered a few toys after reading some of the other builds on this site.

    I'm getting this odbII bluetoooth to monitor the various engine parameters.



    This blue tooth receiver, so I don't have to plug in the tablet to the stereo just get it in the car and it will sync up.



    And also, because right now I'm adjusting the volume of the system with the volume up/down buttons on the iPhone, I got this in-line RCA volume control so I can just pot the volume down with an actual knob and not have to fumble through the touch screen menus to turn the system down.



    I'll update as I make progress. I would eventually like to make the bezel hinge out for easy swapping out of the touch screen. And after that figure out a way to keep the unit charges when mounted in the car.

    And also I would like a way to use my phone hands free like I did with the old pioneer. Something clean and simple. The best case scenario would to some how use the iphone through the nexus somehow.

          It seems to have GPS built in. It knows how fast i'm going and where I am on the map even when wi-fi is turned off, although the maps stop drawing in new sections when I was testing with the wi-fi off.

            More Progress pic's:

            Installed daytime



            installed Nightime.



            CarHome Ultra has a customizable night mode that comes on when it gets dark and you can cutomize the colors, cool!





            I wired this dual 12v cig lights sockets into the ignition +12v. It sends power to the Tablet and the wi-fi hot spot when the ignition is switched on.

            The Nexus has a built in setting to keep the screen on as long as it's getting power and I have the screen time out set to the minimum 15 seconds to the unit shuts off after I switch off.

            Now on to the issues i'm having.

            When the nexus 7 is plugged into a computer via it's own USB cable it charges, also when it's plugged into it's AC to USB adapter it charges. But if I plug it in to my Belkin or Griffen cig lighter usb ports it wont charge. I guess I have to wait for an official Nexus 7 car charger?!?

            In the mean time I rigged up a 12v to 110 volt converter and plugged it's adapter into that! So it's converting 12 volts to 110 then back to 5 volts! Stupid, but it's working for now.




            I just noticed this today.



            So I assume there will eventually be a docking station available, so When that comes out I can mold that into the dash like Papinist did.

                can you post more pictures of the full install, so I can see the entire bezel with the bracket you modified?

                I was just reading reviews on this and I know this tablet would work great for me, but here are my issues.

                1. It doesn't have a microsd slot, meaning no expandable memory. It does have a miniusb, which you can connect a hard drive too, but I need that usb port for charging. I already have an aftermarket stereo system and a EQ, so I'd just be using the 3mm to RCA adapter to go straight into the eq. Another issue is that i have a flip down video monitor and i have no idea how I'd get the video to it. It just released and unfortunately they don't have a docking system.

                  wow, that thing just came out. I wanted to get one, but I'm concerned about the lack of a minisd for extra storage.

                    You might want to check the amperage on the charger. I think both Belkin and Griffin make car chargers that have enough amps to charge an iPad, but a regular phone charger won't charge the iPad. The Nexus 7 may have similar requirements. Just a thought.

                      These are the only pic's I have of the Bezel before cutting it up. It was the one my Pioneer was mounted in. I basically just cut off everything off the back and left about 1/4" left of the face.





                      Then I tore a couple of old hard drives apart and stole the powerful magnets from them.
                      then I broke the magnets up and super glued them to the back of the bezel. I then glued on some felt, just to sort of hide the silver magnets and make it look a little nicer if its take off and sitting on the seat.









                      These are just strips of elastic from a fabric store. I wrapped them around pieces of magnet and used super glue to hold it together.



                      In the car...





                      Temporary location of my volume knob, till I find a permanent place to mount them.
                      The one on the right is the volume. It's inline between the bluetooth receiver and the crossover.
                      The knob on the left is a remote bass knob going back to my sub amp.



                      Here is a new video I made to show how the bezel opens and comes off.

                        For me this isn't an issue, I'm basically streaming everything from the web, Pandora, Podcasts, youtube, ect. Plus Google has this thing called Google Play where you can upload your own mp3's from your computer to Google's servers, then stream them from the cloud, for free! Up to 250 gigs! You just have to have an internet connection. You can then click a box to keep some of the songs in the built in internal 16 gig ram.

                          There is a setting on the N7 that tells the pad to stay on as long as there is power connected, so when it's in the dash and I plan on leaving it in I plug it in using the mini usb cable plugged into a 12 to USB adaptor wired to the +12 volts ignition on circuit. I then set the screen off time for 15 seconds (the shortest available), so 15 seconds after turning the car off the screen goes off.

                          I also have my Verizon MIFi Hot spot hooked to the same 12 volt source so It's always powered when the car is running. I can't hook up my blue tooth receiver to the power because for some reason IT SHUTS OFF WHEN ITS PLUGGED INTO THE CHARGER?!??!. So for now when I come out to the car in the morning I have to turn on the blue tooth. It will then stay on for a few hours so If I go into a store or restaurant it will still be on when I come back. and it will last a few days before it needs charging.

                          I'm looking for a better blue tooth receiver that will turn on and stay on when it sees power and turn off when power is removed, if any of you have any experiences with better blue tooth receivers let me know.

                            Great job. Do you have part numbers or links to the bluetooth module you used? I've tried several and can't seem to find one that is consistent. Is it battery powered or do you have it wired in?

                            Also a part number or link for that inline volume control would be great.

                              What app are you using for the volume bar at the top of the screen. Doing a nexus 7 install myself. Nice job
