Does anyone know if there is a downgrade path if this upgrade to v2.2 was to wreak havoc? The dealership says I will void my warranty if I attempt this upgrade outside of their service bay. I really need the traffic to work as sold but cant afford to throw away a 100,000 mile warranty. Thanks in advance.
They can't void your warranty - it's illegal. If the download messes up sync they may not cover that part but that's all they could do.
This is a long thread but jmr061 has posted the same updates over on the Edge forum and it's worked so far for everyone who tried it. I'd say it's pretty low risk.
