Fantastic! Thank you Ron!

Does anyone happen to have a saved copy of the product information for the map update? The link on the official website is unfortunately dead. AVIC-Z110BT, AVIC-Z120BT, AVIC-X920BT CRD5009A.pdf I'd like to find out what other software changes might be included in the update before I purchase it myself. Thanks!

I'm afraid it's the same process for cell phones and basically all consumer electronics these days - the manufacturer releases updates for a couple years, and then eventually discontinues maintenance on that product. I think there are a few factors involved: 1. Continued updates may require additional licensing (from NAVTEQ) 2. The user base on older products grows smaller over time so there is less overall benefit 3. Any software update requires significant engineering resources to produce It seems that Pioneer doesn't roll these costs into the initial product price (for better or

Hi Deemorz, Sorry to hear of your troubles Just to make sure, you tried inserting an SD card with TESTMODE.KEY before turning on the radio? If you see that something is running on the radio, I would expect it should check the SD card on boot, although maybe not after the update program starts (unlike during the normal radio application).

Ok, after some tweaking, I got my script running. My active software is in PRG0, so I put the MortScript files from Condi's HackMode into \USER\PRG1\APL: Av.exe, commctr1.dll, coredl1.dll, killproc.exe, MortScript.exe, toolhel1.dll. Then I created the following Av.mscr in the same folder: # VR database rebuilder script ErrorLevel("warn") Delete("\NAND\RW\VBT\EN\EN_US\FINISH.db") Run("\NAND\PRG0\APL\Av.exe") Exit Finally, I added PRG.FLG into \USER. The VR database rebuilds every time now. I tried my alternate idea of copying a known working copy of the VR database every boot, but

I think it will be too hard for me to reverse engineer the VBTEngine.exe interface. I don't have IDA and it seems to be very expensive software so I decided to focus my efforts on forcing the VR database rebuild. I downloaded Condi's HackMode and spent some time understanding how it works by looking over the scripts and the forum posts. I realized that I can use a similar idea to accomplish my objective: Replace Av.exe with Mortscript, just like in Condi's HackMode, except modify Av.mscr to delete FINISH.db and then run the original Av.exe. This way the VR database is rebuilt every boo

I used testmode to investigate the issue further. I found that the VR database is stored in \USER\RW\VBT\EN\EN_US. In this directory, I noticed a file FINISH.db. I discovered that if I delete this file, it causes the system to rebuild the VR catalog properly. So I can carry an SD card in the car and delete this file when the problem occurs instead of resynching the iPod. This is better, but I'm also trying to find a nicer solution. By deleting FINISH.db and letting the system build a new VR catalog, I was able to compare a working copy of the VR database files to a non-working copy - the

Hello everyone, I have a strange problem that I was hoping that somebody might be familiar with I have an X920BT upgraded to X940BT using the official 2013 map update. I have a 160 GB 4th gen iPod classic with about 8,500 songs. The headunit builds the VR catalog fine and iPod voice commands work for around a week, then suddenly it seems to forget all the song/artist/album VR information. Any iPod voice command causes it to respond with "what was that?" or "i didn't understand you". The workaround is simple, but annoying - resynchronize the iPod with iTunes, then the headunit will re

I have the X920BT with the GEX-P920XM and it has the exact same problem. Sometimes the logos show up, sometimes they don't. Sometimes half the logos show up. If I switch to FM for 30 seconds and then back to XM they usually show up again. Very annoying. I guess they didn't fix that bug on the X930BT. If you figure out a solution let me know

If the password is missing from the sd card packaging, you might be able to contact Pioneer and have them reissue it.

I thought that the new map update also added spoken street names to the navigation. Instead of saying "Right turn ahead" it would say "Right turn ahead on Main Street". The 2010 software could only speak freeway numbers. Can anyone confirm or deny this? Thanks!

Vandal, thanks for the great tool and all your effort creating the new logos - it definitely is time consuming! Attached is an updated pack for the Zxxx series that includes the logos for KIIS, Z100, and WLTW. This pack works with the AVIC-X920BT as well. I've also attached the photoshop source files for easy resizing to the other receiver types in case someone is interested. The PNG logos inside are from the XM channel guide PDF captured at 800%. Edit: On second look, I'm not sure if photoshop saved the images at their original resolution, so maybe the photoshop files aren't so useful

I tried to splice in the Onstar mic to my AVIC-X920BT but I was unsuccessful. The sound was very quiet. Searching the internet, someone suggested that it is a powered mic and needs to be biased with 6 volts. I tried constructing a simple voltage divider to bias the mic but it didn't seem to make any difference. Also the mirror is glued shut so I couldn't open it without fear of it breaking. In the end I spliced into the Onstar mic wires under the center console and then spliced in again right behind the mirror and connected the Pioneer mic. It makes for a pretty clean installation.

Every photo editor is slightly different, but usually there's a resize menu option where you can specify the new dimensions. You may have to uncheck "lock aspect ratio" or something similar.

Sorry, I'm not sure about the pixel ratio for the AVIC-X910BT

I have an AVIC-X920BT and I have preset up/down assigned to two buttons on my steering wheel and it works well. Note however, that there seems to be no way to switch between preset lists using the steering wheel buttons. If anyone figures out how to do that let me know

Hello everyone, I didn't see any posts that talked about the pixel aspect ratio of the AVIC-X920BT so I thought I would share this information: The AVIC-X920BT display is 5.3125 Inches x 2.8125 Inches = 1.889 Aspect Ratio The AVIC-X920BT resolution is 800 Pixels x 480 Pixels = 1.667 Aspect Ratio In other words, the pixels are NOT square like on a digital camera or computer monitor. If you simply crop an image to 800x480, it will look vertically squished on the AVIC-X920BT screen. To get the aspect ratio correct, resize your image to 800x424 keeping the original aspect rati

XM recently changed the station name for channel 80 from "Area" to "Electric Area" and now the logo doesn't show up anymore I was hoping there was an easy way to update logos as mentioned for the other headunit series in this forum, but I can't find anything that seems to apply to the X920BT. Anybody had any luck updating the logos on the X920BT? Thanks!

I don't think this has anything to do with the antenna. I think it is a software or hardware bug. I'm using the GM factory installed XM antenna and I still occasionally experience the 1 second alternating silence problem I never had the problem when I was using the factory head unit.

Here's a known issue that VBlue mentioned in another thread where you cannot use voice commands to dial contacts: "The problem is related to the BT connecting before the map OK button is pressed. In this case, when you get in your car, just go to the BT contact transfer screen and re-transfer your contacts. That should clear up the issue." I have an AVIC-X920BT. If the unit was previously on the XM source, the next time you start the unit sometimes the station icons do not appear on the presets on the right side of the screen. Instead the default satellite icon is shown. Rotating throu

I have an AVIC-X920BT with XM radio. Does anyone know if there are voice commands to switch stations or presets? Something like "play XM preset 1" or "play XM 20 on 20"? The manual didn't mention anything about such commands so I'm worried there are none ...but I'm hoping someone can tell me I'm wrong. Thanks!

I agree with tom411. There seemed to be mixed opinions on whether the Onstar mic could be used as an input for the Pioneer head unit, so I cut the Onstar mic wires (at the Onstar module behind the center console) on my 2004 Grand Prix and spliced them into the AVIC mic plug. Unfortunately the signal was way too low and it was barely audible. Someone suggested using a 1k/1k resistor voltage divider to bias the Onstar mic at 6v. I tried that as well with no luck. Eventually I decided to splice the Pioneer mic into the connector on the rear view mirror, so at least I could use the existing m

Ok, I've finished my install and I can confirm the VSS wire is the green one pictured above.

I'm also looking for the VSS wire. Here is the engine compartment with the engine cover removed. I think the TAC module is the black box on the center right of the photo, which falls between the air intake and the supercharger. You can see that I pulled back the wire cover going to the harness. Based on cntrylvr79's description, I think VSS is the green wire in the picture below. Can anyone who has already done a Grand Prix install confirm this? Thanks!

I have listened to both Sirius and XM in various cars and in all cases I find the sound quality is worse than FM; no static, just too much compression. It pisses me off...but at the same time I like the selection, so I guess I will keep my XM subscription for now...
