If you're still not sure, get your VIN and go to With the Dynavin N7/N7 PRO, Dynavin has come up with a way to emulate the OEM head unit in a way that keeps the DSP amp active. Another way to know is if your car does not have stock navigation and your stock stereo has a DSP button on it, then it has DSP.
Note: All M series E39s and E53s have DSP.
Yes! ONLY the Dynavin N6, N7, and N7 PRO units do. The round pin wire harness is included with the Dynavin for E46.ġg: Will the E39/E53 Dynavin work with the DSP system? But if you have an E46, let us know because you may need the flat pin wire harness which is only included with purchase of the extension cable.
(The N7/N7 Pro’s short wire harnesses has one brown end and one black end instead of two black ends.) The round and flat pin harnesses are included with the E39 and E53 Dynavins. If you are upgrading your N6 or N7 to an N7 Pro, you won't need to purchase the extension cable again because it is the same on the N6, N7, and N7 Pro however, you MUST replace the short wire harness (round or flat) that plugs into the car's square plug. Upgrading to an N7 Pro in a car with an existing Dynavin extension cable: Standard practice is to run the signal cables (including the extension harness) down the opposite side of the car from the battery cable. *Be careful to note the location of the battery cable in your car, running the extension harness near the battery cable can cause noise/static issues. All you need to do is go to the main menu > Audio > scroll down and select OE DSP Amp to enable audio through your DSP amp.
