trip on the framework 159

hello everyone, I need information, I have a customer with an Alfa 159 which has a Nav of first generation the one with the CD of the maps, so to speak, now he wants to replace the original one with an aftermarket, the only problem is that the Nav gold there are all the info that are usually on the framework, that is, Trip,time and date info, travel, etc etc it is possible to return these data to the framework as a 159 without navi? what should I do? I thought that maybe by planning the body in the configuration without the ships it could work right?
