I have the same year and model and am trying to do the same. Add Bluetooth,
ipod and rear camera. What I am finding is that our radio is not as advanced enough to handle these things. You can add
ipod, and there are some slick modules out there that look straight up OEM (VAIS). Seemingly can't add rear camera to the nav (limited inputs). Working on that. And as for Bluetooth, the problem that we have with our E7006's is that there is not mute function. So any Bluetooth is seperate of the radio. The closest I have found so far is that they splice into the left front speaker for the phone, add the mic up in the overhead console and put a switch into the dash somewhere. The switch is how you "answer and hang up". Not cool in my opinion. Supposedly the Advent Bluetooth works pretty good. Have not heard good things about Parrot. I am a stickler for things being OEM looking and working. I don't want to cut into things, have switches installed that show, etc. Apparently our model is on the cusp of the updated tech. The Tundras started getting around our model time. The 2008 Sequoias have it all too. I came up with the idea that maybe we can change our head unit out to the new one. Haven't looked into that yet, but will. The new units have the mute, extra inputs,
ipod's etc. But I don't know if the newer head unit will seemlessly replace what we have or if they are compatable. If either of us finds out something, or someone else chimes in, we should post. I doubt we are the only ones looking. Especially since bluetooth, either by headset or integration, is the law here in California starting in July.
