  1. Ok...mystery finally solved. The shark fin antenna is to blame. The new one arrived today and I was able to drop the rear part of the headliner and unplug the antenna and power leads to just try the new one before removing the old one:  HD Radio started working!  I then worked blindly to remove the old antenna, unscrew the 9 torx bolts holding the painted cover on, then moved my painted one over to the replacement antenna, and then finally worked blindly again to get that 10mm bolt back in situ. Using the radio system tests, I'm getting 70+ signal reception where I was getting MAYBE 7 and sometimes 0.  All good.

     

    I don't SEE anything wrong; however, the underside had some aluminum corrosion and there are three little springs on the old one that aren't on the replacement antenna. These are pretty heavily corroded and covered in aluminum powder. Maybe just cleaning it would have worked? It seems like Ford went away from that design on the replacements as those three springs aren't there on the  new one...just to the left of the wire and bolt hole.

     

    Here's the dead one:

  2. The antenna parts should be here this week, though I'm not convinced that is the issue. Using the radio diagnostics and some testing, I get:

     

    Sirius satellite:  works great. No issues. (this apparently is a separate antenna in the shark fin)

    FM Radio: VERY poor reception. I get signal strengths typically below 40 and often 0 or sub 20. Unusuable.

    AM Radio: Good reception. Getting signal strength above 70 most of the time.

     

    It's all very strange. I don't know how the attenuation of FM signals differ from AM and how an antenna could impact one but not the other. If the second antenna line was bad used for radio reception, I would have guessed that AM and FM would be impacted similarly. So, maybe it is something inside the head unit?

     

    More updates as I try to use the old "parts cannon" to figure this out.


  3. I am suspecting the "amp" portion of the antenna in the roof to be busted; or, the antenna isn't getting the power signal from the radio unit. I've gone ahead and ordered a new antenna and new "isolater" that is shown on a parts list. Parts will be here next week, then I'll drop the headliner and swap it out. Back in the "old days", I had a powered FM radio antenna to try to boost FM reception in my apartment. It BARELY helped. However, if I removed power from that antenna then radio reception was almost non-existent. This is acting like that, so I bit the bullet and ordered some parts. Once I have it apart, I'll verify power signal from the radio (blue wire, apparently) is getting to the antenna area.


  4. Sorry (jmr061), I read your APIM thing and I was confused since the GPS signal comes in on the APIM, I thought maybe this was related.  Sorry...I was confused. Gotcha:  APIM does not do anything with the FM signal, only the GPS signals.

     

    I just pulled apart the center console and I pulled the radio. All connections to the back of the unit appeared fine. While I'm not a Sirius XM subscriber, I find I CAN listen to their "advertising" channel clearly. I drove around for an hour and Sirius kept playing. It's my understanding that FM radio and Sirius radio comes in via the shark fin to the back of the radio via two cables. There is one antenna for am/fm, and one for sirius. I get sirius fine. I also get somewhat OK am radio reception. FM is the problem. So, radio unit itself or the shark fin? What could possibly go bad in the shark fin? Maybe it got water inside and it corroded? I'll put the center console section back together and then drop the rear portion of the headliner and remove the shark fin and see what is happening back there.


  5. More diagnostic info. I upgraded Sync to the latest 3.4.22XX something. No change. I went into Sync 3 diagnostics (hold track skip on steering wheel and track skip on the center console), then it beeps and goes into diagnostic mode running a speaker test. I selected the AHU diagnostic and pulled up radio signal strength.

     

    On a particular station (94.9) I get a signal strength of 35 and the head unit locks in on the HD portion. This is the only station that locks in HD.

    On another station (96.5) I get a signal strength of 1 and is obviously quite fuzzy and no chance of locking on the HD signal.

     

    I would suggest the antenna must be connected or I wouldn't get the one channel locked in ok? If I drive around, this station won't stay locked and easily drops, but I can't enter diags when driving.

     

    Opinions? Bad head unit? Is there an antenna amplifier somewhere that might be to blame? It's hard to imagine that a passive antenna could fail in some weird way. Water/corrosion in the shark fin?

     

    In reviewing the installation directions, there is no separate FM radio connection cable, the only separate antenna connection is for the GPS hockey puck thing. My GPS is working. I'm assuming that the antenna signal must be coming in on the giant multi-pin connector on the back of the APIM.

     

    I just compared the signal levels with my '16 Ford Focus.  I am getting 45 for a signal strength on 94.9 AND the 96.5. I get above 40 pretty much across the board on a Focus, but it seems the unit in the Edge can't seem to pull a signal other than one channel. Antenna or head unit issue?  I'd guess the APIM that is bolted onto the screen display, so maybe just a new APIM or new antenna.  Looking at photos online, there are at least two cables attached to the antenna, so I'd guess this is an amplified unit. Maybe the amp crapped out; but, where is it?

     

    Looking at ebay, I see:

     

    https://www.ebay.com/itm/373773058941

     

    Where is this part?  I'm going to guess near the antenna in the roof?


  6. Are there multiple antennas on this car? I know my old Passat had a shark fin and antennas in the rear glass. There must have been a module somewhere that would switch between whichever antenna was getting better reception. Is there anything like that to the Edge? Does the wire just go right from the shark fin directly to the radio? No antenna module or anything? Before I rip out the radio and look, I'd like to get a decent understanding of how the head unit obtains the radio signal.


  7. I've got a 2015 Ford Edge and I upgraded the center system to Sync 3. It was all working, then recently I've noticed that radio reception is essentially non-existent.  It was working fine, but not any longer. Is all radio reception handled by the shark-fin antenna thing? Is there a module that controls reception somewhere, perhaps? I would doubt that the cable fell out of the back, which I'll check, of course.  GPS location is spot-on, but that uses a dedicated antenna. I can try AM radio and see if the problem is there too. Can you get to the antenna on the roof externally, or must you drop the headliner to access. It's not powered in some way, is it?


  8. The coffee was around the cupholder/shifter area.  This is where the plastic clips were missing in a few places.  The center stack itself appeared untouched.

     

    Yes, I had a Sync 2 system with Ford Touch...no car play or the Sync 3.0 stuff.  The touchscreen on Ford Touch requires actual pressure on the screen for "touch" as you have to press two panes of "plastic" together.  The new screen is capacative touch, like any modern mobile phone.  You just barely breathe on it and it registers.   This was pretty much plug-n-play, except for the initially-wrong gps antenna.  Yep, $650 included them pre-programming the APIM module as I had to submit my VIN to them upon ordering.  It took about 9 days for the screen to arrive from China to Seattle.

     

    The directions they shipped with the unit aren't that great or specific to my vehicle, but there were a few youtube videos I watched that provided a lot of help on where the clips were located.  It's really easy.  I could pull the unit out of the dash in less than 15 minutes now without breaking anything.

     

    If you can install a car stereo, you can do this. 


  9. Cost was $650.  All parts were brand new, the screen says made in China on the back; but, the original Sync 2 screen also said "Made in China" on it, so I'm pretty sure it's a factory part.  There were cheaper options, but this one looked legit, for some reason.  It also came with a ODB-II-to-USB cable, should they need to remotely connect to help you diagnose any problems using Teamviewer and probably a hacked version of Forscan.  I didn't need that level of support, only a different GP antenna.

     

    All the steering wheel controls work, voice commands, climate, navigation, and audio system.  This replaced the current usb/aux/sd-card with a usb-c and usb port. That's fine, frankly.

  10. I bit the bullet and bought a Sync 3.4 upgrade kit off of ebay.  The kit included the screen, the APIM module, a usb hub, a GPS antenna, and some pry tools.  It was clear that somebody had been into the center console before as I found some clips missing some some plastic was broken.  Nothing that major and I was able to order all the proper clips from the dealer and used some glue to affix a clip.  Not a huge deal, but I wonder what they were doing?  There's clear evidence of a spilled coffee as well, so maybe the previous owners were trying to clean all the junk out of the center cup holder area? 

     

    Anyhow, things went pretty smoothly.  I located the GPS antenna in front of the dash storage tray.  Some online video put stuck it to a location that I didn't think would hold for very long, so I laid mine flat by the speaker grill in the dash.

     

    I have practice as I had to basically do the installation twice due to an error by the seller.

     

    Upon initial installation, if jumped right into the car and started it immediately, I'd get a "Navigation is not functioning properly" error.  If I waited about 30 seconds before starting it, then it was fine.  The seller said they sent the wrong GPS antenna (even though it DID work after you ack'd the error).  The new antenna arrived and I had to take the dash apart again.  The new antenna is shaped slightly differently, but everything works 100%.  No issues or niggles.  Works great!

  11. My Edge is in the shoppe for a recall (steering bolt corrosion) and I had them try to look it up. My vehicle does fall within the water ingress issue based on manufacture date (April 4, 2015).  Geez, only a few weeks away from when Ford identified and remedied the issue in the factory.    I see that 15B21 recall was performed to check for water dampness.  The vehicle failed the dampness test.  A few months later, the car was in the dealership again with "related damage vehicle hold".    The dealership worked on the car for 14.7 shop hours where they did the following:

     

    "Perform recall 15b21.  Leak Verified.  Apply urethane sealer to a-pillar.  Repair vehicle per wet vehicle repair instructions"

     

    I suspect that the owners got the option to have their vehicle purchased by Ford.  The '16 models were just about to come out and those included Sync 3.  I know if Ford was going to buy my car back and I could get a new one with an upgraded ICE (in car entertainment), I'd take it.

     

    Still looking for further information.  Does anybody have more info on this leak issue?  Can you inspect the vehicle and tell what's been done?  Is this leak from the passenger side, drivers side, or both?


  12. So, I didn't notice anything odd on the Carfax after I selected a used 2015 Ford Edge.  When cleaning the vehicle, I see the following sticker:

     

    edge-sticker.jpg

     

    I am the "third" owner.  It appears the first owner only had the car for about 6 months, which then Ford apparently bought it back, then the next people had it until just last month when I bought it from them.

     

    So, this vehicle apparently was a lemon-law return.  Is there any way to find out which repairs that the dealer couldn't finish that triggered the lemon law?  I had no idea that Ford would put a sticker in the door jamb for this.
