Model Two Owner's Manual
Will cutting or bending the Model Two's InfiniMount brackets void the war-
ranty or harm the unit?
No. The RetroSound® patented InfiniMount bracket system has been de-
signed specifically to be bent, cut and modified to simplify radio installation.
Modification to the radio's brackets is actually encouraged to ensure proper fit.
For questions about modifying the bracket system, please feel free to contact us

I have your radio with an amp connected, but hear a whining/buzzing sound
through the speakers when I step on the accelerator.
If you have an external amplifier installed and experience a high-pitched noise
that varies with the engine's RPM, there are many possible solutions:
1. Make sure the amplifier's gain controls are not turned all the way up.
Amplifiers amplify everything, including noise.
2. Make sure to run the amplifier's low level input cables (RCA's) separately
from the amplifier's power wire.
3. Try grounding the amplifier near where it is installed.
4. A low level (RCA) noise filter, known as a "ground loop isolator," is often
effective at removing engine or alternator noise.
5. Try a filter on the amplifier's 12 volt power lead. Make sure to use a filter
that includes a ground wire.
6. On rare occasions, noise can be introduced through the antenna lead. If
disconnecting the antenna makes the noise go away, you need to replace
or repair the antenna plug where it goes into the radio.
When I plug in my flash drive, the screen says "USB ERR" and it won't play the
files I placed on the drive.
1. Make sure the files on the drive are .mp3 or unprotected .wma (Windows
Media Audio) files. iTunes files are .m4a format and need to be converted
to .mp3 format, which can easily be done using iTunes.
2. Verify the capacity of the flash drive. The Model Two will play 1 gig up to 32
gig size flash drives.
3. Make sure the flash drive is not NTFS formatted. Always use the FAT32
format (most drives are formatted with FAT32 from the factory). Be sure
to do a full format rather than a quick format, and check that none of the
files or folders have names longer than 64 characters. It is very important
that none of the audio files have DRM. Use only MP3 files or unprotected
Windows Media format files.
