I have been reading the forum and the key people here seem to say downgrade to 520. Well I asked Chad about it at Classic Cadillac and he said you can't get it anymore.
Is that true?
I have had the flashing ready on 535, but a hard reset fixed it. I recall when 535 came out the members here were saying update as it balances the cells(?). do we have a Pros and Cons list of these 2 codes?
Why should I downgrade? Do I need to be on 520 for the new Infotainment offering from @PowerSource
