Does anyone have the possibility (or knows from their own experience) of what the accessories with the article numbers Art.- No. 30786701 and Art.- No. 31296156 and Art.- No. 31268489 (refitting kit return camera for 5 inches – screen) cost? I find the accessory, but no price at all, and would like to know before I start with it, because if it is too much, I will let it be. MfG charles164
