Hey guys,
Bought RNS 510 B version couple days ago, very pleased with unit.
Just few questions:
1. Sometimes I can hear cooling fans kicking in after I remove key from ignition, last about 10 min and after unit completely off. Is it normal?
2. I believe after cooling fans are off, I also can hear noise in speakers (it is sounds like someone turned amp off). Is it normal?
3.Unit runs 4020 firmware and V8 maps, what is latest firmware for B version?
4. Also want to add factory bluetooth, which one to go for? I have highline MFD and MFSW
Thanks
