Using the map switching feature has ZERO impact on the cruise control, it should still work exactly like before. If you got the ARC features as well it is possible that there is a bug that needs to get ironed out, but I haven't heard of anyone losing cruise completely.
Another possibility is that the tuner flashed your ECU with a rom that was from a Z without cruise.. so now your car thinks it doesn't have cruise either.
Long story short, get ahold of the tuner.
