Welcome to the Raymarine Forum mauruuru,

The membrane of which you have spoken of is part of the R62185 UniController assembly. For the benefit of others who may be viewing this thread, please note that this part is no longer available. In the past, should the membrane have failed or any of the plastic parts comprising the UniController assembly have failed, then it would have been recommended that the entire assembly be replaced. As the part is no longer available, it will no longer be possible to do so, necessitating that one consider replacement of the MFD. This assembly is secured in place over the UniController's circuitry by a pair of phillips head machine screws which may be accessed by removing the MFD's bezel. Adhesive was used in construction of the C/E-Series Widescreen MFD's UniController assembly. The recommended adhesive to use is Loctite 401. Care should be taken during application to not apply adhesive membrane's rotary seal or to any part of the membrane regularly flex when the trackpad is used. Accordingly, you may want to consider dry-fitting the seal prior to applying adhesive.
