Bests & Worsts Reviews from Amazon

My wife drives a 2007 Suburban and we had been trying to figure out how to connect her phone to the ONSTAR system. We had a free year of Onstar through our Insurance and while we had it, I bought 'minutes' from GM so she could use the phone system built into the car. But we really wanted to use our own cell phones and the ONSTAR unit in my wifes car did not have the Bluetooth option. I spent several months talking to dealers, ONSTAR, and a GM Rep to see if her unit could be upgraded. I offered to pay for the unit and for two years of ONSTAR if they would just upgrade the unit but was repeatedly told "NO". I know it could be done as I had read stories of owners getting newer units from salvage and doing so. While ONSTAR was nice when we had it, there was no way I was going to pay for it if we could not use our phones. At that point I began looking for systems that worked with ONSTAR that would allow me to use my own cell phone, there are none! I then looked at possibly replacing the SUV's stereo system with a model that had bluetooth, while there are options that did so none of the units would use the SUV's built-in ONSTAR microphone system. As I continued my research I found the BLUESTAR unit. I contacted the company and after corresponding with the person who started the company I ordered a unit. When the unit came in, I opted to have a local shop do the install as installation involved removing the front console panel and I did not want to take a chance on damaging my wifes SUV. Two hours later the unit was installed and I began testing it. The unit works PERFECTLY. It paired up immediately with my Samsung Galaxy and acted just like a regular bluetooth headset. When you either press the telephone button on the mirror or on the steering wheel, the Galaxy would prompt me "What would you like to do" and I could tell the phone to either CALL [Contact Name] or DIAL [Number] or whichever command you wish just like a regular bluetooth. When a call is coming in, the stereo plays a melody and the call number is displayed on the dash and you can answer via the button on the steering wheel or on the mirror. When you make/receive a call - Your stereo is automatically muted and your AC/Heater fan motor speed is lowered so the background noise is lowered. Best of all - The onstar Microphone is used! I later paired the unit with my wifes iPhone and the results were the same, everything worked perfectly! Highly recommended if you have an older onstar Unit! 10/09/12 - Update - My wife upgraded her iPhone to a 4S Model with OS 6 and the Onstar worked without an issue. So at this time I have tried it with an Apple 3G, Apple 4, Apple 4S, Samsung Glide, Samsung Galaxy and Samsung Galaxy Note (All Samsungs had the ICS build of the Android OS) and all have worked without an issue.
