Thats pretty cool. Microbypass has a interface to do this automatically now. I do like the james bond style though.

Until Pioneer changes the timing sequence with a firmware update and renders your bypass ineffective. They have apparently done it a couple of times already. Just be aware.

Thank you, I understand your concern, but Pioneer hasn't changes any software on the 8400 or appradio2 regarding the bypasses. I have both of these radios, and the microbypass interfaces work perfectly on both. Our store is the one of the top Pioneer retailers in all of Florida, and we now use these microbypasses on every Pioneer radio install we do. They are just as cheap as a tr7, and you don't have to program them. They are simple three wire connections and work right out of the box. The original appradio1 is the only one that has issues with bypasses and has software changed (i heard their making one for this radio though). Have you ever sold a customer a tr7? lol, its a hassle to do the tech support on that one. With the microbypass, even a customer can install it. Its that easy. Just my opinion.

fyi MicroBypass has their new model selling already for the Appradio2 sphda100. I purchased one, and I can confirm that it works on my sph-da100 in my truck. IMO it is way easier to use something this small and not have to program it like the tr7 and still add a relay. If you want them to build something custom for the timing sequences of the app radio1, I am sure they will. They are really easy going and offer great customer service. For my money I want something easy.

I wouldnt try that... its just the wrong way to do it..... Its like fixing fuses in the car by wrapping tin foil around them... on a $800+ unit?, Its like driving around on a doughnut spare tire in a supercar. You can buy an extra pin on microbypass's website so you don't have to molest the harness.

MicroBypass has extra pins for sale with instructions if you don't want to remove the mute wire. I was using mine for onstar, so I needed a pin too. They have the oem pins from Japan.
