So We rode the bike to work today 150 miles total. Its not a full review as i still need more time to learn the device and use other features. but here are my first impressions
Installation - Very simple yet time consuming if you want a clean install, You have two options for the initial install. You can use a 2 way tape that's provided or you can clamp it. I did the clamping method "Stronger hold".
Parring - Parring My iphone was really easy just like any other BT. Parring both G4 systems was A pain in the ass, but that was my fault for skipping the instructions. i just glanced at them and went for it " bad Idea". after so many tries. I sat down and read the whole manual. after the initial parring was completed. I decided to Use the Stereo Bluetooth I played a song on my iphone and Viola wireless music streaming no strings attached.
Radio - If you buy this device because of the radio Feature, then go get your money back. because it really sucks. You only get crispy clear station on things you don't want to listen to. don't get me wrong its ok at times but for the most part its useless. But its better then nothing.
Speaker's & Mic - They are great, I was on HWY 5 doing 85 mph with ear plugs on and i could still here my wife just fine. the mic is great if you place it away from the wind or else you get a lot of wind noise on the other End. The kit came with another Wind canceling foam that goes on the mic but i did not use it since I had a full face helmet.
So far my wife and I love this thing its a must have for people who do 2 up often, long commutes or long rides on vacation. No more yelling just to tell you they have have to pee

. on the way back we hit some light showers for a few miles and it was great to know she was doing fine the whole time. We still need to learn how to use some of the features correctly, at times she couldn't switch between us talking and having her Iphone play some music. at one point she had to get her phone out and try resetting the phone and the G4 system as it did not play the music. after like five minutes she got it and was good the rest of the way. I think a lot of this issues can be fixed once we get to know how the device really works, what buttons to press and which ones not to press. The battery life lasted for the whole 3 hour of riding we did. well that does it for the First impression of the G4 BT system. So far i have been very impress with this product Just talking to my wife the whole trip made the ride even better.Just be sure to read the instruction over and over because it has a lot of features and it can get overwhelming on the first try, just trying to remember every button to press and how long to hold the buttons for is enough for someone that's not technically incline.
