  1. AVIC Z130BT Tuner issue

    More research is pointing me to the TDA7706 digital tuner chip that sits on the riser board ... if this chip is fried then it's beyond my electronics skills to replace something like this. A shame, it looks like this is available from multiple sources on eBay for under $5.
  2. AVIC Z130BT Tuner issue

    Okay, I took the unit apart today. Actually much easier than I was expecting it to be ... please note the following: * There are only two sizes of screw heads, Philips #1 and #0. Use GOOD screwdrivers! Many of the screws, especially the smaller ones, are in very tight, I almost stripped one, so a cheap philips screwdriver may not cut it here. * To release the display from those first two screws at the bottom you have to separate the metal holding tabs a bit to get them off the posts that the screw goes into. this is a tiny post that allows the screen to swivel against the holding tabs during the opening/closing action * The unit is made of surprisingly few modules, and they are all connected by ribbon cables. Take your time with the ribbon cables, there are three types of connectors that I ran across: - flip lock bar, flips up to release cable from holder - pull out bar, pull it out towards the ribbon about 1/8" to release the cable from holder - pull out, the ribbons with a hard blue plastic tab at the end of the cable ... these you just pull out * I've attached a photo of all of the screws I removed to get to the AV PCB assembly. Not a great many screws. Fyi I made a makeshift adhesive screw holder by alternating masking tape strips face up/down on the paper ... works great. I could not see anything visually wrong with the AV PCB ... the antenna jack seems to be attached with large solid solder joints, no burn spots anywhere that I could see, nobulging capacitors. I am posting a bunch of photos of the board, if anyone has a suggestion on what to inspect more closely let me know and I will look and/or post more photos. Also, while I have the unit disassembled, if you have interest in what any of the other components look like let me know and I will be happy to take and post more pics. Thanks. John
  3. AVIC Z130BT Tuner issue

    I've had the same issue for several years ... the radio came back once or twice for a few months, then eventually went out again for good. AM and FM both exhibit the same problem on my unit. which points me to the component that brings signal into the unit. My Traffic tuner seems to work fine with the Nav unit, so that tells me the antenna on the car is fine. Today I pulled the unit from the car again since I would like to get it fixed one way or another ... first I tried removing the Traffic tuner from the signal chain and plugged the car antenna directly into the unit, no change, so the issue must be inside the unit. Looking at the Service manual I found the "AV PCB" board on p272 that appears to have a simple two-prong connector for the antenna cable jack. I've attached an image of that page from the manual. I wonder if it's as simple as solder joints on that connector. So before I send this off to a repair shop I figure I should take a better look at it in case it's something I can handle. Next up, I will disassemble the unit using the instructions from the Service manual starting on page 149. The instructions are actually pretty clear so I'm not thinking this will be very difficult or risky. I will send an update when I make more progress. Thanks. John
  4. Turn your Z110bt into a smart TV!

    Sounds very interesting (the full app mirroring at least) ... does the 2017 release have this capability in it already or did you have to apply extra mods? Thanks. John
  5. I've had the occasional hassle to reconnect bluetooth. If you haven't received better suggestions already, try this -- After the phone is paired, turn off the car (and radio), rebooting your phone, make sure your phone isn't connected to another bluetooth device, and then start the car/radio. I don't have any technical explanation why this might work other than it should reset the drivers and hardware on both sides and then allow a connection attempt using the proper sequence.
  6. I first tried "ABC" and it didn't work, so I used "PASSWORDPASSWORD" as originally specified and it worked.
  7. Sorry, my bad -- I misread the instructions and was hoping to bypass the extra No-Nag bypass step. Thank you for the prompt response ... all is good now. Installation completed. Nag screen removed as well. Donation sent. Fyi I used a SanDisk 8GB SDHC card for this, formatted on MacOS (MS-DOS), also distribution unzipped on MacOS.
  8. I'm trying this now and getting the infamous "Incorrect SD card" error at the end of installation -- * z130BT, starting with v6 (2015 maps?) * I ran the Shortfuse script, worked like a charm ... thanks! * Downloaded, unzipped and loaded the 2017 files onto an SD card. Overwrote Navi.exe with the Nag-free version. Popped it in, used the special password, and it went through the installation all the way up to "98% - 3 minutes left" and then said "Incorrect SD card installed ... please install the correct one.". I searched the forums and found some suggestions related to card size and format: I don't have a 4GB card on me, but I do have an 8GB SDHC card, I formatted it on our Windows machine FAT32 with default allocation size. I also unzipped the distribution file under Windows as was recommended. Still no luck. Do I really need to find a 4GB SDHC card to load this distribution on? Or is there something else I am not trying? I will gladly contribute to the pool once I can get this install completed successfully. Thanks.
  9. My tuner went out a couple of years ago with a big "Pfffzzzttt!!!", has no signal whatsoever on FM or AM, the tuner just sits on the lowest frequency number with it's spinning icon, with no audio, no static, nothing. I assume something blew on the Tuner IF Unit. There is a service shop on eBay that says they will fix any problem for $130. Plus cost of shipping the unit, that's going to run me close to $150. Now I don't mind tearing my radio apart to replace the board myself. Not only will it be cheaper, but will also save me two weeks of not having a radio in the car. In the z110bt service manual the part number listed for the "Tuner IF Unit" is CWN4824. Pioneer's web site sells that part fo $65. I have read that the z110 thru z130 all share the same physical components, so I would assume this part is good for my radio. Can anyone confirm the CWN4824 part number is correct for the z130BT, and for the US market? Do you know if I can get it for a better price from anywhere other than Pioneer? Thanks. John
  10. Z130BT FM HD Radio issues

    Old post ... have you fixed this problem since? I have a 2005 Mercedes C-class, our cars have an antenna amplifier built into the car, but as ChicagoAndy says in his point #1, you have to connect your "remote out" lead from the head unit to that corresponding wire in the car's harness in order to supply it with power to amplify your signal properly.

    yes I did it to my x130BT. unchanged behavior after the software update to 5.1
  12. Will external Hard drive (ie. WD Passport) work?

    I think the issue is that there are folder and file count limitations on USB or SD ... iPod is an external device that manages it's own file system and therefore avoids those restrictions. What I don't know though is if you can display and navigate the iPod directory structure on the AVIC screen in the same way you do with USB or SD. With bluetooth from my iPhone I certainly cannot -- so I have my USB and SD cards loaded to the hilt.
  13. Gapless MP3 playback

    Any word on if/when the AVIC units will be able to do gapless mp3 playback? And any idea if this is can be done in software? My iPhone does it quite nicely, and I have many albums that could use it. Thanks. John

    It knocks out the voice command NAVIGATION features only ... you cannot enter a destination by voice, only by typing in on the screen. Supposedly if you have not implemented the parking brake bypass hack, you can only set a destination while the parking brake is on -- therefore no practical reason to try to set a destination by voice command and hassle with all of the misinterpretations of what you're saying, when you can just punch it in on the screen. I have the bypass hack on my unit and I haven't missed the nav voice command. I only use voice command for making phone calls.
  15. The software upgrades are to the stock binaries, which means any software hack you implemented on the previous binaries will be gone and you will have to re-implement on the new binaries. So, if you implemented the software break bypass hack then you should have to re-implement.
