Umh....sorry

The new series (nuvi 34xx,35xx,x0,24xx,25xx,and other....) only work with JV split screen.

The map 2013.20 (NT) do not exist file JCV split screen. Not work this file JCV on new series.

Therefore:
1) new series (with split screen) and map 2013.20 nothing JV
2) new series (with split screen) and map 2013.21 work JV, but with its appropriate for the model

Bye,bye
