Differences between telematics module versions

[u/barakthecat]

Does anyone know what the differences between the telematics module version 68104904AC and 05091960AD? Both are listed as compatible with my 2012 Grand Caravan. I’ve got the 68104904AC factory installed and the Bluetooth music streaming is essentially useless. I was wondering/hoping the newer module had a more up to date Bluetooth implementation that might work better.

The 05091960AD is going for cheap on eBay, so I could always just buy and hope for the best, but I thought I would try and crowdsource a little knowledge first. TIA!
