[GUIDE] HowTo Make a Mazda RX8 Streak

---

This guide represents a current WORK IN PROGRESS. Development is currently underway for Streak 7 OTG functionality including consideration for FTDI Serial2USB kernel module and HU Integration via custom Android Activity & Service, and breakdown of the Home Dock for stealth installation and OTG support.

While this guide focuses on Streak integration with a Mazda RX8, the concepts, tools, and many of the components can be utilized for a multitude of other platforms.

MODS: If you'd rather this be in General or Apps & Themes, feel free to move it. Simply bear in mind that I plan to provide source and binaries for a custom FTDI kernel module (if necessary), steps for installation, as well as source and binaries for any Android Activities and Services I build for Integration.

I've been running a Windows 7 mini-itx carpc for quite some time on my RX8. The system consists of a ITX case I keep mounted in my trunk, USB GPS, RS232 to OBDII wired connection, a Grom Car2PC HU Integration adapter with a bunch of custom code for HU and Steering Wheel controls integration, and a Lilliput 7" Resistive touchscreen mounted in a Mazda Japan Retractable Navigation tray.

I deliver clean power to the PC using a Carnetix P2140 power supply with a bit more custom code for ignition synchronized hibernate and wakeup.

For the past year I've been waiting for a good Android tablet replacement and have landed on the Streak 7.

Dimensions wise the Streak 7 matches the typical Lilliput 7" exactly.

This project requires the following additional hardware for your RX8

• JDM Retractable Nav Tray
• SlipGrip RAM-HOL Mount
• Streak 7 Dell OtterBox (Commuter)
• Streak Home Dock *
• 3.5mm Audio cable (possibly with MIC splitter)
• Grom Car2PC Adapter

Here is a picture of the Streak running OBD2 and HU Audio integration via the Streak audio out jack and a bluetooth connection to a generic ELM OBD2 reader.

What works?

• Car Mount complete
• Head Unit Audio via Streak 3.5mm audio out

What is in-progress?

• Dell Dock breakdown
• PDMI extension cable (if required)
• Power supply integration
• Power state change Android Activity

What is planned?

• USB OTG Support via dock
• FTDI USB to Serial Kernel Module
• Car2PC Integration Android Service

You need to mark and drill two holes on the JDM nav tray's center plate for mounting the SlipGrip Streak holder. I also used a wood shim to provide a solid mounting surface between the center plate and the holder.

Here's a shot of the Navigation Tray fully assembled, ready to be installed in my dash.

Remove all Center Console components.

Wiring and Mounting complete (temporarily using the Streak 3.5mm audio plug for HU integration to my Car2PC module).

And all stealth like when not in use.

If you're planning on taking apart a multimedia dock, I'd be interested in high/higher res scans of the pcb and the wiring diagram of it for the wiki.

Some of it's pins are known, but the info is all over the place

I've got a DLSR so no problem. I'll be out of town for the next couple days. Should have an update by next Friday.

Nice work so far; looks very clean and professional. Are you running Torque app in there?

I have torque lite installed... Have been using dash command too.

Sorry for the delay... finally got to dismantle my dock and take some pictures.

Hope to have it integrated this weekend.
