So I installed a 12" uconnect 5 from a manual hvac uconnect 4 8". Everything works as it should except the hvac is full h
ot or full cold. Is this normal or can it be fixed? I know I can do the auto climate upgrade to help but is that the only option? I had some people say there hvac mixes air after upgrade but some people say it will not work.
