Motorola MDRMN4025: a microphone for the existing GM fleet
When the radio is working in the car and the handheld microphone is worn out or missing, purchasing a separate accessory can keep the current workplace. MDRMN4025 is one of the positions for such an order: select it from the station model, the old microphone and connection, and then agree on a specific configuration.

What does the MDRMN4025 code mean?
Motorola’s accessories catalog for the GM MDRMN4025 series is listed as a functional compact microphone. This is a guide for selecting a hand accessory, not the designation of the radio itself. The microphone code should be written in a separate line: the request for “Tangent Motorola” leaves too many options.
The same directory describes the hot mic function. Its operation for the installed station must be checked against the documentation and configuration of the particular device; the purchase of an accessory does not in itself confirm the availability of the function. Do not transfer the characteristics of a nearby impact-resistant or keyboard microphone to the MDRMN4025: these are other positions.
Appearance helps to prepare the application
The illustration from our card shows the body, twisted cord and plug. It helps to explain what class of accessory is needed, but does not replace the photo marking the proposed instance. If you have an old microphone, remove its designation and connection to the station. For a fleet of different cars, add a model of the device to each photo.

MDRMN4025 and GMN6146: Similar appointment does not mean replacement
Motorola describes GMN6146 as a handheld microphone for car adapters. Therefore, it is impossible to choose between codes only according to a similar body. In the case of GMN6146, the application also requires an adapter code. If only the old microphone is known, start with photos of the station, adapter, and connection; matching the seller agrees throughout the kit.
You don’t need to buy GMN6146 as a universal replacement for the MDRMN4025 or extend the selection of one position to all GM, DM and other families. With unknown marking, it is better to first install specific equipment and then choose an accessory.
What do you get in the quotation?
Please indicate the full microphone designation, product status, scope of supply and available quantity. If you need a holder, attachment or individual accessories, list them. Catalogue photography does not prove that all the details shown will be included in each order.
Replacing the accessory and buying a new station are different lines of purchase. If the device is serviceable and the task is limited to the microphone, start with the accessory. If you need to equip a new machine, separately coordinate the station, power supply and other positions on the installation conditions. References to GM340 At the bottom, they help move to this scenario, but they don’t make the station a mandatory part of the order. MDRMN4025.
