The optical parking system (OPS) is available for the Polo. The system was used for the first time in the Passat CC. The optical parking system is a software extension of the parking aid system. The driver is supported not only acoustically, but also optically.

When equipped with parking distance warning system, the Polo has ultrasound sensors at the rear. The parking distance warning system therefore only detects objects that are behind the vehicle.

OPS is achieved by the parking aid control unit evaluating the distance information according to sector and transferring it to the screen. The BAP operating and display protocol is used on the CAN data bus for this.

The visual images are displayed on the screen built into the radio or navigation system. This is possible with the RCD 310/510 radios and the RNS 310 navigation system.

The advantages of the optical parking system:

- The position of obstacles is displayed in relation to the vehicle position.
- You can manoeuvre the car using the display.
- You can simply look at the screen to see the current state.

## Onboard supply control unit

Like the onboard supply control unit in the Golf 2009, the onboard supply control unit in the Polo 2010 has been expanded to include numerous other functions. In addition to the functions of the convenience system central control unit J393, the function of the data bus diagnostic interface J533 (gateway) is now also integrated in the onboard supply control unit J519.

Even though a large number of functions have been combined in a single control unit and housing, the hardware scope has more or less stayed the same. The onboard supply control unit is connected via two 73-pole connectors.

There are currently four equipment-related versions:

- Basic +
- Medium +
- Medium ++
- High+

A large proportion of the bulb power is controlled by the onboard supply control unit using integrated semiconductor switches. In the current version of the onboard supply control unit, that is the turn signal, brake lights, side lights, tail lights and the reversing lights (automatic gearbox). Each function is switched by just one control unit output (1 PIN), e.g. all three left-hand turn signals.

On the Polo, there are, however, also bulbs that are controlled conventionally by mechanical switches, i.e. light switch E1,for example, dipped beam, full beam and daytime running lights. The remote control aerial is integrated in the new onboard supply control unit. The radio aerial is not a separate wire aerial, instead it comes in the form of a circuit board aerial. Integration in the onboard supply control unit also allows a reception range of 30 to 50 metres.

### Location

The previous location under the left-hand side of the dash panel has been kept for the new onboard supply control unit.

The scope of functions depends on the equipment. The higher equipment levels are expanded by the listed functions.

| Equipment | Scope of onboard supply control unit functions |
| --- | --- |
| Basic + | - Terminal control - Load management - Control of brake lights, side lights, parking lights and interior light - Control of turn signal and hazard warning lights - Wiper control, front and rear - Control of horn - Control of rear window heating - Control of door control units - Boot lid release - Data bus diagnostic interface - Powertrain and diagnosis CAN |
| Medium + | - Central locking (control of locks, doors and flaps) - Enabling of seat heating and tilting sunroof - Control of windscreen washer system - Control of front windscreen heating - Control of door LIN data bus - Control of roof LIN data bus (rain sensor, interior monitoring, inclination sensor, panoramic sliding roof) - Exterior mirror heating - CAN convenience |
| Medium ++ | - Remote control (aerial integrated in control unit) |
| High+ | - Shiftlock, starter inhibitor - Cruise control - Control of anti-theft alarm LIN data bus - Control of reversing lights, static cornering lights, fog lights |
