Troubleshooting Guide for Installing Dension Products
32
When installing a Gateway 500, please do not forget (!):
- Gateway must be the last connected device on the MOST ring, or other devices like Amplifier,
Phone, Navigation, etc. will not be accessible when the Gateway is active
- if a factory CDC is installed, always install the Gateway beside the factory CD-Changer
- double check the light directions on the MOST ring
- power needs to be constant/permanent 12V
- take care because BMWs have 2 different kinds of switched power – one of them goes OFF
immediately as soon as the key is removed from the ignition – the other goes OFF after 15
minutes (!)
- set the proper DIP settings, always press the reset or disconnect from the power for a while
when changing DIP settings
When enabling, please keep the following in mind:
- The Gateway 500 emulates a CD-Changer (in most cases, expect BMW where it operates as
an iPod device) therefore this option needs to be programmed in the following vehicles:
 BMW
 Mini
 Mercedes (sometimes)
 Porsche
 Saab
- The vehicle needs to have a factory CD-Changer – otherwise the GW500 won’t work:
 Volvo
- Sometimes the CD-Changer needs to be physically installed during programing of the CDC
option – afterwards it can be removed:
 Saab (it can be located in the front or at the rear)
In most cases the enabling procedure can be done using an official service computer, however we
recommend the use of Autologic when enabling in a BMW, because
- there is a Dension Gateway installation specific coding menu on the enabler
- the service managers at BMW usually do not have sufficient experience to do the programming
because it can be done in manual programming mode only.
