Application and compatibility

This roof antenna mount for the BMW 1 Series E81/E87 LCI is designed for vehicles equipped with a satellite navigation system and radio. The OEM design allows for installation in place of the factory antenna without the need for body modifications or installation.

The element comes from a car with low mileage, which translates into limited wear and tear and preserved functionality of the antenna system.

Structure and function of the element

The roof antenna base is responsible for:

• stable antenna mounting to the roof covering,
• transmitting the signal from the antenna to the radio-navigation installation,
• sealing the mounting hole against moisture ingress.

Thanks to the factory design, the correct geometry and shielding are maintained, which promotes the correct operation of the audio system and navigation in typical road conditions.

Technical condition and benefits of choosing a used part

The BMW roof antenna base offered is a used, functional part, originally disassembled. These components do not contain mechanical components that wear out quickly, so when properly installed, they can continue to function like new.

The choice of the original used antenna base is:

• maintaining the factory quality of fit to the roof and installation,
• reducing the risk of compatibility problems compared to substitutes,
• a favorable cost-to-durability ratio for an element with a simple, proven design.

Installation and operation

The roof antenna base is designed to be installed in its original location, making servicing easier. When replacing it, we recommend:

• checking the condition of the seal around the roof opening,
• checking the wiring harness for abrasion and corrosion of the contacts,
• verification of the correct operation of the radio and navigation after installation.

A correctly installed part helps maintain stable signal reception and reduces the risk of roof leaks in the antenna area.
