Wrong.
Sunt 3 tipuri de module DAB, deși funcțional sunt cam la fel, form factor-ul e diferit
- unul pentru Medianav gen 1 - inaccesibil utilizatorului obișnuit, retrofitul presupune și alte piese
- unul pentru Medianav gen2,3 și 4
- unul pentru Medianav gen 4.5
Deși nu ar trebui ( R&D-ul se face pe cont propriu, nu mură-n gură) niște informații din datasheet-ul cipului principal :
xxxx is a DAB/DAB+/DMB-audio baseband and audio processor for automotive applications, where both DAB to DAB and FM to DAB service followings are required. It integrates dual enhanced hardwired Eureka-147 demodulators and a programmable audio decoder which supports various formats, such as MUSICAM, HE-AAC V2 as well as MP3, WMA into a single chip. With this dedicated architecture, xxxx supports seamless switching between two audio streams with the same contents.When service following takes place between DAB, DAB+, DMB-Audio and FM services, xxxx can detect time difference between two same audio contents and jump to the synchronous point, so the audio contents can be presented without discontinuity.
A 32-bit RISC processor is also embedded to take care of internal operation as well as user applications. xxxx also includes an internal SDRAM, so that no external working memory is required.
xxxx is designed to operate in slave mode where it can be controlled using serial interface (SPI, I2C, UART). Flexible product configuration is supported by enriched interface such as serial interfaces including I2C, SPI, UART and IrDA, I2S based audio input and output interfaces, and non-volatile memory interfaces (NAND flash, SD/MMC).
