Hey guys...Hoping you can help me out here. I have an opportunity to get an RNS-510 B version for pretty cheap and I'm wondering what the differences are from the C version. Will I be able to upgrade the firmware on the B version and are there any drawbacks?
I have a 2011 CC R-line but want to have factory navigation and for the price, I don't know if i'll run into another unit for this price. Thanks!
