1 Introduction
This document shows an overview of the VP2Refresh radio system.
The VP2Refresh is a multi media radio with an on board Bluetooth chip from CSR which support the
Bluetooth version V2.1+EDR with a max. data rate up to 3Mbit/s in EDR mode.
1.1 System description
The Bluetooth chip in the VP2Refresh system is implemented for hands free audio and data connections
with mobile devices like mobile phones.
The basic function of the VP2Refresh Bluetooth system is the hands free functionality in combination
with the car internal loudspeaker and microphone.
The Bluetooth IC work with an 26MHz crystal.
The following pictures show the VP2Refresh radio hardware with the housing:

1.2 HW/SW information
The VP2Refresh radio system is designed for use in several countries with varying HW variants
dependent to the car model and car internal accessory variants, for this reason the VP2Refresh could be
delivered with different HW and SW version (e.g. BT radio connect with main board PCB antenna or with
antenna on the front PCB).
For the Bluetooth certification a variant with antenna on the front PCB will be used.
The HW / SW version is marked on the top label see figure3 (e.g. SW:20.00.26.01, HW:F.EU.D2.V22).
For the Bluetooth RF radio part at VP2Refresh only one HW version exists, this version is defined as:
“Model: VP2Refresh”, see figure3 label.
