Hi, owns a car radio of the brand alpine d106r, connected with navi module alpine 009series and dvbt module t150dv. Unfortunately I can not switch to navi or dvbt, because I did not get a remote control. There is a lot of remote control but which I need so that I can switch to dvbt? Can I use the 4191 multi-function remote control ? Have read that I have to switch to AV the 4191 has no AV key Can it not switch on the display. urgent help. Thanks in advance
