Nuvi American English audio versions, difference?

 

My Nuvi 200 has 2.20. My 205 came with 2.20 as well, but after installing "American English" voice through WebUpdater, it rolled back to 2.00

2.20 is smaller in size (1.06MB) compared to 2.00(1.16MB).

What are the differences and why did WebUpdater roll it back from what was already installed on the unit by default?

I had a similar experience

I had a similar experience and now I've lost Jill! She was so less boring than Samantha ... which happens to be my name. laugh out loud
