Make sure it is the G3 version before anything else. If not email Gap and they offered a trade in program. With the new software release earlier this year it provides that same functions I use it for on my LR4. Reset service, parking brake service release, add a key (yes it works on the D5!), pull codes, and add items to the CCF. No issues switching between the LR4 and D5 when used and second VIN added.
