1 Factory Radio
A direct-fit replacement head unit for 2007-2008 Cadillac SRX models with AM/FM radio, six-disc CD playback, auxiliary input and navigation
This remanufactured head unit replaces the original AM FM radio with six-disc CD player, auxiliary input and navigation in the 2007-2008 Cadillac SRX. It carries part number 25837571 and interchange number 638-01663, matching the factory option code U2V. No unlock code is required for operation.
The unit fits only when the vehicle currently uses part 25837571 or one of the listed compatible numbers 15901844, 15932202 or 25797598. Different data streams or external amplifier configurations will prevent coding even if plugs appear identical. Verify the part number against the existing radio or supply the VIN before ordering.
The receiver restores AM FM reception, six-disc CD playback, auxiliary audio input and built-in navigation exactly as equipped from the factory. It does not add Bluetooth, satellite radio or modern smartphone integration beyond the original auxiliary jack. Buyers needing streaming audio, hands-free calling or additional media formats must look elsewhere.

Turn the ignition on, verify the display illuminates, tune to a known AM and FM station for clear audio, insert a CD into each of the six slots to confirm loading, playback and eject, then test the auxiliary port with a portable source to ensure sound comes through all speakers.
The remanufactured radio chassis with part number 25837571 is supplied; mounting brackets, wiring harness, antenna adapter, navigation DVD disc and any vehicle-specific trim pieces are not included and must be obtained separately.
Choose the unit marked with part number 25837571 and interchange number 638-01663; it matches the U2V option code and compatible part numbers 15901844, 15932202 and 25797598 for those model years.
