Hi there, i am new to g35driver but would really appreciate the help

I have a 2007 g35x the had a weak battery and i was boosting it for 3 days in a row. Woke up one morning boosted it again and than i realized my radio was completely gone no sound nothing from the cd, radio, satellite radio no sound was coming out. I went and replaced my battery thinking that would change.. and nothing still not working and now every time i turn on my car everything is off such as the heating. Usually if i leave the heat settings turned on or high and i than turn on my car later the heat will be running.

Just wondering if anyone knows or has heard of this issue and what i may have to do to fix it?

Thank you for taking the time to read this!

 

Forum guys - does the V36 CREw have the ribbon cable issue we have on our V35s?
