System of pluggable modules for cars to update it with latest technology
Car lifetime is much longer than multimedia solution lifetime. Because of that multimedia systems mounted in the new cars, after couple of years are obsolete. For example, in pre-AD2P Bluetooth systems for cars support HFP profile (hands-free system), but are unable to support audio playback or music remote control. Since in car's lifetime Bluetooth standard can change several times, replaceable modules might provide new functionality to older cars.

Current known solutions:

1) replaceable radio systems adhering to ISO 7736 and ISO 10487. In this system user might insert or replace radio unit of his choice and connect it directly to car's speakers. Drawbacks:

- modern car often do not support this system, since it interferes with car's interior design

- car radios using this system tend to occupy much more space than needed

- those systems are not integrated with other car's systems, like Navigation, climate control or car's computer system Advantages:

- well established standard

- new radios can support latest multimedia technologies

2) OBD (On-Board Diagnostics) Bluetooth adapters, exporting some of the OBD to smart phones.

We propose to implement replaceable multimedia blocks of well-defined purpose, connected using common bus. Blocks might be categorized as:
- storage: for example, CD-ROMs, CD-ROMs, hard drives, ssd drives, MMC slots etc.
- video presentation: including monochromatic displays, color displays, touch-sensitive displays - communication: Bluetooth adapters, Wi-Fi hot-spot, NFC module, GPS/Glonass, GSM module - processing unit: memory units, CPUs, GPUs

All those units might be interconnected using common, high-speed, standardized bus. When

new module is available, user would buy new module, open some sort of encasement, remove old module and insert the new one. The new module would then register in the system and present it's capabilities to the rest of the system. Thanks to this solution user might for example upgrade his Bluetooth module to support new functionalities and better bandwidth or improve accuracy and speed of finding his position using A-GPS/Glonass module instead of just using GPS.


- Better granularity: you can replace just a piece of your system, thus reducing the cost of upgrade
- Allows to upgrade your car with technologies not yet present during car's manufacturing

- Helps adjust your car to your every need

- There are no "hacks" or workarounds, after upgrade the car does not loose warrant.

The idea works as follows:

The system consists of two major categories of objects:

1. Core system, providing communication functionality with feature (module) detection

2. Modules, performing well-defined tasks and exporting predefined interface to the core system.
