3. Don't panic, you have to remove your unit once more time - first time for NAV, A/C, and Radio initialize and linked all together - and reconnect it.
4. Reset your ECU - removing negative terminal for about 30 second only- your unit will be fully working again. PM me if you need more help!

This didn’t work for me. Fuses in and out are good. Could the battery be bad again? I bought it 9 months ago but never hooked it up til 2 weeks ago. Insufficient power/battery source?
