This must have cost a fortune.

You sound like you might be the rare individual who can answer my question. Can you think of a way for me to get Bluetooth connectivity for my 2006 Zephyr with factory non-nav THX-certified system? I tried this: http://www.crutchfield.com/I-rXYEc000/cart/EmailCart.aspx?emKey=1280062 And here are the items in your Cart: 541ISFD531 PAC ISFD531 05-Up Ford/Linc/Merc Dual Input Intrfc 822BTREC Milennia MIL-BTREC Bluetooth Adapter But it sounds like garbage. I A/B'd a song on CD and the same song streaming from my phone (320kbps), switching back and forth between CD input and AUX 1. Major volume drop and it seems like half the speakers are gone even though I don't think they are. Volume was maxed on phone and player, I also tried the 3.5mm wired input (AUX 2) which was worse, if anything.

Cheap, quick, & easy:

I want to add streaming capability to my Zephyr but the stock system has no Aux input. I don't want to use FM modulation. I do want to retain the THX feature. I'm considering swapping my system for the 2007 Nav system which has Aux. I realize this requires a different bezel. I don't know whether nav will work. I'd love for it to work, but it's not my priority. I'd use a GROM or iSimple type system in the Aux for BT streaming audio from my phone. I don't care about phone calls, I don't need a mic. I'm also considering aftermarket options incorporating a Maestro unit in order to retain the THX feature. Has anyone tried anything like this?

Aftermarket is an option but I don't want to lose the THX feature. Has anyone used a Maestro unit to retain THX with an aftermarket unit?

Thanks, that's valuable information for me. If I go with an aftermarket unit and ditch the factory unit, I assume my THX-Certified features go with it, eh?

I believe I've answered 2b, it appears a different bezel (2 DIN) is required. I can get a factory bezel for the nav version. I think this will work, but I'm not sure if the nav will be operational.

This car has no great spot for it and its got weird vents. If you search "universal phone mount vent" you'll see a clip version and a magnetic version of one with a split cone that slides over the vent (I'm describing it because I don't think my attempt to post a picture while I'm on my tablet is going to work). I've ordered it but haven't gotten it yet. Fingers crossed... http://i.ebayimg.com/00/s/NzU2WDEwMDA=/z/m3wAAOSwv0tVSdY-/$_12.JPG

I just bought a Zephyr and it's perfect, except I really need to be able to stream audio from my phone. The 2006 doesn't have an Aux input, which makes this problematic. My factory unit is THX-Certified without navigation. I don't care about phone integration, I don't need to add a mic. If I get a call, I'll hear through the speakers and they'll hear me through the phone mic. I've read a post in another forum where a guy said that he installed a 2007 factory unit in his 2006 with no problem, so I'm assuming that this is a possible solution. Is it possible for me to swap my factory 2006 non-nav unit for a 2007 navigation unit by simply plugging it in with the existing setup? In other words, is the bezel/cutout the same size for nav and non-nav units and are all the plugs the same? I realize the nav won't work without the accompanying CDs with the data. Although nav would be nice, the priority for me is to add a streaming option. I would also prefer a touchscreen to the interface on the non-nav unit, so even if I cant use the nav function of the nav unit, I would prefer the nav unit for that reason. I would love to get the nav working, but I don't know if the feeds (speed, location, etc.) in my factory non-nav vehicle exist or not. That is, I don't know if all that I'm missing for nav is the head unit with nav, or if there are other features required for nav which don't exist in my car. I'm not interested in any FM modulator solutions, and I want to retain the THX-Certified functionality, using all 14 speakers (if, in fact, that's what it's got - I only see 10). Here's a summation of my questions: 1. Can I put a 2007 non-nav unit in my 2006? 2. Can I put a 2007 nav unit in my 2006 which currently has a factory non-nav unit? 2a. If yes, will the nav work? 2b. If yes, will it fit in the 2006 non-nav space without modification? 2c. If yes, is any wiring modification required? 3. Has anyone added Bluetooth streaming capability to their 2006 or 2007? Any favorite solutions? Thanks, everyone. If I can get this going, this car's going to everything I could want. It's nine years old so that might sound crazy but I'm coming from a 2000 Continental, which is a great car but its old and I had a 1/4"-to-cassette to get audio in that baby!
