06,330i BMW Radio, navigation systems are not working after battery ( replaced 10 days ago), starter and alternator replacement(last 6 months). Car had failed to start, after jump start it worked for 2 days and failed again, jump start helped. Any insights to fix? I was told by a mechanic that codes are not resetting and electrical systems are having an issue. Yes, Codes would not reset back to zero such as break or flat tire. I was also told they checked the fuse and it all looked good. BMW Expert technician might be able to answer quickly based on their past experience, anyhow, this car needs a fix. Thank you.
