It should be fine, especially if you consider upgrading to the Nautilus range in the future. The CDMCNT matches the CDM1/CDM7 better than the CDM9 while the HTM2 fits the N805 and N804 better. The CDM9NT is just sort of in the middle. The HTM2 is a better sounding unit than the CDMCNT, with the voices sounding more natural so why not use it?
