20053 (or below) is for the 3 hour unit
30022 (or above) is for the 6 hour unit

The prompts are different, so a 3 hour unit can not be "upgraded" to Version 30022. There is also a difference with chip ID and memory mapping between the 3/6 boards which "may" cause memory addressing issues. They are 2 different boards with 2 different versions, is the CCR time out option worth chancing another returned unit?

IMO, they did it poorly. The part numbers are still 3534-00 & 3038-00. The only way to tell is the software version screen or a remaining recording time >3 hours. And it has already caused a few questions.
