An easy way to retrofit bluetooth to your stock system

If you want to stream music from your phone through your stock audio system, this is what you need. The instructions weren't very specific to my G35 sedan but with some googling, I was able to piece it together (the reason why I dinged it one star). I didn't want or need the microphone for bluetooth calling so that saved me a lot of time and hassle routing the wire through various interior panels and trim. The install is pretty easy if you don't mind climbing into your trunk and pulling some carpeting and trunk panels lose. The sound quality is great.

Update of Update (unfortunately)

See pros below. Installed by Authorized USA Spec dealer. Install was great (70 minutes). Mic quality on phone excellent (installed at mirror). Small learning curve as booklet directions are not for earlier G35's. Some trial and error needed. Sound quality on streaming phone media (Pandora/Slacker Radio) better than Sirus/XM. Bluetooth or 3.5mm quality equally good. Unfortunately CAR BATTERY DEAD after 30 hours. Had to remove battery from car, charge, reprogram ECM, reprogram windows, sunroof, and idle air adjustment and all radio presets.(looking forward to that bill). Car is back in garage with trickle charger waiting for replacement from Crutchfield and installer to remove existing radio, test for current draw and install new unit and test draw again. This is a known problem - check Crutchfield's site for other similar reviews. I love having to pay people twice to do the same job! My advice for installers, check current draw first before any other work. OBDPII scan devices will usually give that information. UPDATED 8/13/18: Quality control issues may leave your car stranded - I have received a second unit. Works with NO problems. Sound quality excellent, bluetooth connection excellent, 3.5mm jack works fine. A test of the usb port for charging also was also positive. (not using) Most of time bluetooth connection takes less that 5 seconds. Mike placement above mirror, sound quality and reception has been problem free. Familiarity with operation now makes it easy to use. Tapping the "tune" button as opposed to holding it down or up is all it takes. Overall very satisfied for a none OEM. Crutchfield Customer Service is as good as there is. UPDATED 2/21/19: 2nd unit exhibits same problem as first. Battery drain issues. after installing the second unit I replaced a good 520 Amp hour battery with a 720 amp Hour!! AGM battery. Unfortunately after 8 days unused in a garage the battery was totally flat. My other car with a 8 year old battery outside in 4 degree weather is starting fine after 28 days. Some assistance from the good folks at Crutchfield would be helpful.

Battery Drain if Idle for 2 Days

I this installed in a 2005 Nissan Mazima which is acceptable per USA Spec. I chose this model instead of the BT-45 NIS because it can be installed via the SAT harness located in the trunk of my car (I have the Bose sound system without navigation). No need to pull the dash. Very simple install in the truck. The unit works great. Absolutely love the sound quality, etc. BUT it will drain your battery if you do not drive your car within two days of turning it off. The battery draw with the car turned off is .15 amps, FYI I've worked extensively with USA Spec to resolve this problem. They had me do a work around on the harness wires which kills the 12v constant draw (used for memory settings). It worked, so no battery drain now BUT this also kills the memory for presets.. specifically the voice command function which defaults to enabled every time the car is turned off. My wife is hard of hearing so when there is an incoming call, the voice notification is blaring. I can go through the cumbersome process to disable it each time I start the car but that's a pain. My wife says she can live with the enabled voice notification but it is a safety issue to me. We'll try it and see how she likes/dislikes it. Hopefully she won't be jolted outta her skin when she gets a call. Bottom iine is.. if you drive your car within 2 days of turning it off you'll good. If you're retired like us or you just don't drive your car for two days, you'll run into

Great way to add aux input and bluetooth

I bought this adapter for my 2005 Infinit G35 sedan. I have the factory Bose stereo with no Bluetooth or aux inputs. I needed to add an aux input to play music from my Android phone. This adapter has both a wired aux input ( 3.5mm jack) and supports Bluetooth audio streaming, which basically is a wireless aux input. It also supports Bluetooth phone functions. I don't use Bluetooth for phone calls in my car so I can't comment on the phone functionality. The Bluetooth audio streaming sounds outstanding in my car, much better than I expected. The wired aux input also works and sounds excellent, but that what I expected from a wired aux input. Installation: This interface is designed to emulate the satellite radio input of your stereo. It doesn't replace the existing satellite input if you already have a satellite receiver, but instead adds an extra "satellite" input. The bad news is that the Mastersheets from Crutchfield don't cover this type of installation. The good news is that Google is your friend, and you can find this info on some of the enthusiast forums (like g35driver.com). Once I determined the satellite connection point, installation was easy. Also, the instructions from USASPEC are written for Infiniti/Nissan vehicles that have "Preset A-B-C" buttons on the radio, and instructions for switching between aux and Bluetooth are for that style of radio. Mine doesn't have that button so switching between them is different - use the "PTY/CAT" button.
