| Anyone use the PAC AAI-GM9?
I have a 2002 Escalade with Bose system and OnStar, just wondering if anyone has used this unit, it doesn't specifically state whether it works with Bose system or not.
Here is the description: The AAI-GM9 allows direct interface of any preamp level audio source to a GM factory radio with a slave unit, eliminating the need for sound degrading solutions like an FM modulator. The AAI-GM9 interface inputs sources from units such as a DVD, VCP, MP3, Satellite Radio or Play Station. OnStar Ready. When OnStar is initiated, the auxiliary audio inputs are automatically overridden to allow the OnStar audio to be heard. Unlike the 'cut and splice with relays' setup, with the AAI-GM9 you will never miss a phone call. The AAI-GM9 will work even if the vehicle does not have OnStar. Lower cost and higher quality sound than a FM modulator. Perfect for SUV’s like the Escalade, Tahoe, Suburban, Denali and Yukon. Comes with a three position switch which allows you to switch between two auxiliary inputs and the factory slave unit. High quality audio isolation IC eliminates engine noise. Internal CMOS electronic switching for long term reliability. Completely plug & play. Requires no external wiring. Small size for easy installation (5 X 2 X 1). Requirements: The sedan or SUV/truck factory headunit must have a separate working slave unit which uses the GM 9 pin connector (1995-2002 vehicles). Slave unit examples are: external CD changer, cassette player and/or single CD player. Please note that the slave unit must continuously be playing for the AAI-GM9 to work.
and what the heck do they mean the slave must be continuously playing for it to work??? |
