[hide]Overview
This project encompasses single and double DIN stereo decks meant to interface with a smart phone and provide a customizable experience tailored to the wants or needs of the user.
Single DIN Unit
This unit utilizes tight integration with the smart phone to deliver audio and other services.
Features
- Uses wireless charging to keep your phone topped up while being used as your headunit (no cables!)
- FM reception using the vehicle's antenna (via BT or via microcontroller via BT)
- Hands free calling operation via BT
- Audio playback/control via BT
- Auxiliary headphone jack or RCA input
- Jog knob for volume
- Dual momentary toggle switch for next/previous
- Can integrate with a BT OBD2 reader for displaying car info
- Can use the OBD2 integration with a WiFi/BT camera for backup cam
- Google maps on your dash!
Parts List
- Single DIN mounting hardware
- BT A2DP/AVRCP/HFP receiver with custom wiring for the jog knob and toggle interface
- Wired MIC for HFP
- Microcontroller
- BT module for microcontroller (RFCOMM connection only)
- SPI/I2C/UART controlled stereo audio switch(Possible Solution)
- SPI/I2C/UART controlled FM receiver(Possible Solution)
- 4-6 channel output stereo audio amplifier
- Phone mount/charging hardware
- Air Dock recommended for qi-compatible devices
Pros
- Lower cost
- Wider options for devices
- Smaller footprint
- More space for controls
Cons
- No dedicated device/requires that the phone come out of your pocket
- Storage restricted to on-phone
- Requires phone/tablet at all times to work
- May be possible to do dumb aux passthrough by default
- Requires tight integration with the device (custom apps at the least)
- Smaller screen for less mapping awesomeness
- Lower quality audio for HQ sources
Double DIN Unit
This unit utilizes a much more loose integration with the smart phone and uses only standard interfaces to communicate with it.
Key Features
- Uses wireless charging to keep the tablet topped up, tablet is necessarily integrated into the dash
- FM reception using the vehicle's antenna (via USB or via microcontroller via USB)
- Capable of reading USB storage peripherals
- Hands free calling operation via BT
- Audio playback/track information/control via BT
- AVRCP1.5 features like browsing would be nice, but probably limited to 1.4/tag info for now
- Auxiliary headphone jack or RCA input
- Jog knob for volume (is there space for this?)
- Dual momentary toggle for next/previous and FF/RWND (is there space for this?)
- Can integrate with a BT OBD2 reader for displaying car info
- Can use the OBD2 integration with a WiFi/BT camera for backup cam
- Google maps on your dash!
Pros
- More storage options
- Dedicated unit for operation
- Better integration into car
- Able to interface and work properly with any smart phone that has BT
- Larger screen for more mapping awesomeness
- Higher quality audio for HQ sources (USB DAC)
Cons
- Higher expense
- Tied to specific tablet
- More space
