I ordered a "iSimple ISFM21 TranzIt Universal Bluetooth Enabled FM Transmitter Car Kit for Android Devices, Blue" today to install in my 2005 CTS, V6 3.6L . Has Nav, XM etc.

I looked throughout these forums and saw the many options, this seemed to be an easy install and I would prefer bluetooth to AUX install I have seen some people doing.

My question is has anyone installed one of these before? How do you like it? Any tips? I am going to be attempting to install this myself! I'll post some pics and let you guys know how it goes.
