Navi Install

[Shane Rouse]

Naviuses threading, to speed up downloads; It pulls 50 asset chunks on 10 threads and since the vulnerabilities per assetfluctuate this can spike the memory above 2G. If this happens increase your memeory to 4G for under 10,000 assets and 8Gb for larger asset counts..

I'm still working on a fix for large accounts, those over 100K assets. For now use the thread option to avoid DB locks by reducing it to 1. Increasing your RAM and running Navi on SSDs will speed help avoid DB locks.

Navi 6.3.0 was recently tested on a container with 250,000 assets and 41 million vulnerabilties.

It took 30 mins for t.io to prepare the download and 30 mins to download and parse the datainto navi.db which ended up being 31GB. Plugin queries took 2secs where looking for text in an output took 2mins.

I want to install an AUX connection on my car navigation system. I have never done such thing before, though. I searched a bit around and a very similar installation to what I need is here on Saabworld.net. However, I don't have that cassette player but a navigation system, so the board looks different. I haven't really played around yet but I thought I'd ask some more experienced people if they see from the pictures of the board and/or the connectors whether it is obvious where to soldier the AUX input connection.

Edit: Thanks to a hint, the head unit might not have any audio signals at all on the board. From here you can see that the main unit is in the back of the car. Edit: From other sources, I have read that it is possible to install a telephone headset. This must be somewhere in the front of the car. Some more information about the telephone input is here. Some more about the audio system in general (but which mostly just confuses me) is here.

The communication between the different parts is via the (I)-can protocol. There is the Saablin project - a small Linux - which has reversed engineered the protocol and enables usages such as to install a line-in (by emulating the CD changer). For example, see here. A similar project is an Arduino project here. However, that might be overkill for me.

I only have pictures from the outside yet as I haven't yet uninstalled and opened it. However, these pictures are already interesting. You have two cinch connectors there which look very much like a line audio input. There is also some not-connected plug with 5 pins (or so). Maybe that is for telephone and it would enable the cinch audio input somehow?

Or, from the input adapters here or here, I'm not sure whether they might already fit to some of the connectors. (It says there that it is for Saab 93/95 from 2006-2009, but mine is a Saab 95 from 2004, so not sure if it is compatible.)

Or, is the whole unit just digital and the digital-analog conversion is done somewhere else in an external amplifier? I think that 6-pin plug is the output. I'm not sure if that is something digital or analog.

If you look at STC-700 Internal Schematic PDF (I am not vouching for the source/site) This is the actual audio/control unit of the system. The Head Unit does not do anything with the audio directly. The DV2200 is just the GPS Nav System.

So one of two things could be happening. The system is set up so that the 4052 multiplexer is always used, or it's only used when the main ic knows there is a cd changer involved. For the most part, the 7407 can directly access the CD IN line which is tied to the NAV, so the multiplexer is only needed if the cd changer is present. Hell, I don't think it's needed at all, but I'm not a highly paid car stereo engineer.

IF it's the first case, you could tap into the 4052's extra input X/Y3, add a resistor and switch to Control Line A (tie it to ground through a resistor, and tie the switch to the pin and the 8v used), and once you enable it, you should hear audio when you are in Nav mode. This might cause you not to hear the nav when it is trying to speak.

Edit:The DV2200's service manual (Full schematic and pcb) (Again, not vouching for website) shows that the back connectors are Video and Audio. The Yellow rca connector is Video Out, the Black connector is Audio Out. Same audio tied to the DIN connector on the right of the rca connectors (Pin 8 and Pin 12, R & L Audio to CD IN R/L, but both are tied together at the NAV so the same signal to both sides)

It might just be coincidence, but there's a 20-way connector on the unit, and the ISO C (miscellaneous) connector is also 20-way. (Though I'd not blindly follow the ISO pin numbering if I tried anything with it, but I'd certainly look at it).

ACC - Accessory - +12V swithced by the ignition (stage 1 / 2).PARK - parking brake (some functions - eg video - might be disabled when the parking brake is on).ILL - Illumination - lights up when the car's lights are on.ILL-CONT - (real guess this one...) illumination control (variable brightness if the car dashboard brightness can be varied).BU - Backup perhaps - constant +12V to keep the memory (eg radio stations) stored when the unit is off.REMO - (nothing immediately springs to mind on that one).

After creating a backup, Naviextras Toolbox will start downloading and installing the selected updates. A double status bar shows you the progress: the one on top shows the total ratio of the job already done, and the one at the bottom shows progress with the current file. Please wait until you receive a message that the operation is completed.

Here you can find all the files related to map contents and other extras that are already on your device or those that can be updated with your latest purchases or free updates.

In this menu, Naviextras Toolbox allows you to select and install individual items from a purchased package in case you choose not to install everything (e.g., because of the lack of free space).

navi allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands, with argument values prompted to you. It uses fzf under the hood.

If you don't have access to bash at the moment and you want to live preview navi, head to this playground. It'll start a docker container with instructions for you to install and use the tool. Note: login required.

The Naviextras Toolbox is a Windows-based program designed to install and organize content on your device. It enables you to install free updates made available by the manufacturer of your navigation device. It also enables you to purchase a wide variety of extra content, including maps, 3D content, traffic information, and road safety cameras. Once connected to the Naviextras Toolbox web store, you can browse and purchase items that are compatible with your navigation device. In addition, the application enables you to upload your own points of interest to your device, to remove unnecessary content, and to make a backup to avoid any data loss.

This guide leads you through the above actions.

The Naviextras Toolbox prompts you to update at startup if there is a newer version available. If you choose to update, you will go through the same installation procedure as described above. You must be logged in to be able to update the software. If you are notified about an available update but can find no way to complete it, please contact your internet service provider.

The pipe was so easy to install. The quality is second to none and the matte black makes it look so clean. The sound and pop is crazy, the only caveat is that it is a bit too loud (at least for some of the neighbors) and I already got stopped by the cops on the first run. Hopefully I can find an insert to quiet it down. But other than that, this thing is worth the price.
