Hello have already read in the forum a little bit what adapters from Yatour or Grom. Do you have something new on the mark? But I would like to have an FM transmitter, what you can operate via the radio. Now the question about the radio. I drive a Volvo S 40 II Built 10/2004 with the 2.5 L suction cup and 140 Ps. What is there for a radio installed? Where is it installed and where are the adapters connected? At the front of the CD drive or somewhere in the car where the radio is located? Do you also have possibilities of double DIN radios seen with Navi and all Pi Pa Po climate display and everything integrated for about 300€ but do not believe that this really works and trust me with the bus and so not to. What would you install what is good and cheap (they e-bay) and how do I connect everything? Thanks Andreas
