What you need is:
- Apple 30 pin to Lightning adapter A1468; $15 to $30 on eBay. Make sure you get an Apple genuine one. The fake ones will not transmit sound to the A3; merely recharge the iPad.
- Dremel tool.
- Velcro strips. I used the two-inch (5cm) wide ones.
- Double-sided tape. This is what I used, 2.54cm wide:
- A can of spray paint to paint the Apple A1468 adapter. I recommend this product and color: ultra matte black.
- An iPad 6.
- Painter's tape (paper-based adhesive tape).
Steps:
A. First, you will see that by pushing the dock connector on the A3 to the "device locked" position, you can plug the A1468 into the A3 connector; however, you cannot push the adapter into the cavity into the "device unlocked" position; it doesn't fit. Also,
familiarize yourself with using several fingers as you "unlock" the A3 to push down all three ejection pins (the plastic movable surfaces that are on the sides of the dock connector) so that these can lie flat as you (in the future) insert the iPad into it.
B. Use the Dremel tool to slightly (very, very slightly) enlarge the aperture. The A3's plastic erodes very easily and very quickly. Just go lightly right around the aperture once, and you will see that the A1468 now wants to go into the cavity, but perhaps a bit askew. Abrade the aperture just slightly where you see resistance.
Do not needlessly enlarge the aperture any more than needed. This part should be done in five minutes or less. Outcome: the A1468 will slide right into the cavity, up to the limit of the A3's dock connector lever up to the maximum "disconnected" position. About a third of the adapter will still protrude from the cavity.
C. Connect your iPad and test for functionality: the A3 should reproduce sound nicely.
D. On A3's cavity, on the far side from the dock connector, but still within the B&O logo and regulatory materials sticker (it is a very large sticker, and you can remove it to install a new battery, and stick it back on), stick two parallels strips of 2.54cm double sided-tape. Your tape will end up measuring 5.08cm wide (2") by about the width of the large B&O sticker.
E. On top of that initial layer of tape, lay a second layer of exactly the same dimensions. This is to thicken the base to which the iPad will adhere.
F. On top of that second layer, add a 2" wide stripe of velcro, to match the length of the stripes of double-sided tape.. I recommend you make it the hard side of the velcro. On the iPad's back, adhere a matching "fuzzy" or "hairy" strip of velcro.
G. Finally, push the dock connector to its "unlocked" position; i.e., the A1468 slides as much as possible into the dock connector cavity. Insert the iPad into the Lighting connector, a bit askew towards the "up" side when the A3 is laying on its side (like on the 2nd photo on the 1st post). Once the iPad is inserted in the connector, lower the iPad so the velcro catches. The reason you inserted the iPad with a bias towards "up" is that when the A3 is on its side, you don't want the velcro to let the iPad sag downwards. You want the iPad perfectly horizontal.
H. Once you are satisfied with the disposition of the iPad on the A3's cavity, the final step: remove iPad and connector, protect the 30-pin side with a very slim strip of painter's tape, and entirely surround the Lighting contacts with painter's tape. Clean and then spray-paint the connector. It is best to start the spray a few inches away from the connector, and quickly pass over it, and then pass again. Each pass needs be fast enough that the connector will not immediately blacken in one pass: but several passes will blacken it. Let dry 24 hours.
I. Repeat step G.
You are done. Bear in mind, repeatedly removing and inserting the iPad, which can be done at any time, will result in the black paint scratching off and exposing the original Apple white, which is unsightly. This is why once the iPad is installed, it should live on the A3. But if you scratch it, no problem! Just repaint.
The iPad 6 is inserted, the A3 is fully functional as designed, and the iPad 6 is 100% secure: it absolutely will not fall from the A3 even if inverted. It is being held by the A3 factory slots designed to retain the old gasket, except the slots are now retaining the glass/aluminum directly. The iPad also sits perfectly symmetrical and even in the other dimensions.
You could use your A3/iPad like this forever. The "bottom" part of the iPad is held, as per the A3 original design, by the dock connector itself. The "top", by the slots.
I couldn't. The lack of depth symmetry would drive me up the wall. I just can't.
Since I can't use the slots for holding, my alternative is velcro. Originally I used two full layers: a fuzzy side on the A3, then a hard side velcroed into it, then a hard side adhered to its back, and then a fuzzy side on the iPad. Too much! The iPad, quite secure, stood proud. The exact opposite problem of the photo above.
The solution was the two layers of double sided tape plus the one full velcro layer (hard side adhered to the top tape and fuzzy adhered to the iPad). The iPad sits slightly proud, but almost unnoticeable. I can live with it.
