Where to do the coding and/or installation: at service stations or by Dension installer partners (www.dension.com/automotive/where-to-buy)
- Mercedes and Porsche require coding of the CD changer option, if the car never had a CD changer before.
- Saab: if the car has or had no CD changer, then an original CD changer is required with a service computer to enable the CD changer option. The CD changer can be removed after programming.
- BMW requires generally the IPOD option to be programmed, but no coding is required for the Gateway 500 Lite if the car had a CD changer before, or the CDC option is coded. For programming IPOD we recommend Autologic, but if the BMW’s made year is late 2005 or is newer, then you can also choose the Dension GEN Enabler Tool (GEN2BME).
