Well, design with LCD type of display is not an issue. Even it is made in compact size, making room and fixing in that place in dash will be on user side. I can not do more remotely. Further, some user are so smart to handle this type of installation while other may not so. Rather if it is provided in as whole unit , it can be place at available place on dash.
I take some time and make a kit with LCD (if parts found in markets). I offer u this then lets see how u blend gadget at ur end in dash, if u are interested
