| Subject: | Radio Upgrade Service Procedures |
| Models: | All 2000 Saturn L-Series and S-Series vehicles |
Purpose:
The purpose of this bulletin is to provide proper service information about
radio upgrades for the Saturn L-Series and S-Series vehicles.
The L-Series and S-Series designs utilize the same 2 radio levels that are physically
interchangeable:
| • | Base radios: AM/FM (UM7) and AM/FM/CD (U1C) |
| • | Up-level Radios: AM/FM/Cassette (UL0) and AM/FM/Cassette/CD ((UP0) |
Notice: The optional remote 6 Disc CD Changer/Player will only operate with an Up-level
radio.
2000 S-Series Audio Systems
The S-Series has 2 different speaker designs:
| • | Base speaker system (UQ0) |
| • | Up-level speaker system (U79) |
S-Series vehicles with factory installed AM/FM Base radio (UM7 and U1C) come
equipped with the base speaker system (UQ0). If upgrading from a base radio (UM7 and
U1C) with the base speaker system (UQ0) the speakers should also be upgraded to the
Up-level speaker system (U79) to assure appropriate sound quality.
2000 L-Series Audio Systems
The L-Series has 2 different speaker designs:
| • | Up-level speaker system (U78) |
| • | Advanced speaker system (U67) |
The L-Series Up-level speaker system (U78) is designed for use with all radios.
The L-Series advanced speaker system (U67) is designed to only be used with Up-level
radios (UP0 and UL0). Base radios (UM7 and U1C) cannot be used with the advanced speaker
system (U67). To assure proper sound quality, matched systems should be used.
