Title: RNS510 Noise?
Post by: Munzz on December 25, 2014, 06:18:56 pm: Evening All,

I fitted my RNS today and all is well but I noticed that when the engine is off I can hear a slight buzzing noise from the unit itself; either the hard drive or cooling fan.

I have a new CAN Gateway so I hope this won't cause the battery drain issue but when I tried to start my car it did struggle, although managed to start.

Is this something to be concerned about or could it have just been a cold start issue and a coincidence!?

I've logged details of my unit below.

Thanks all, and Merry Christmas.

I had a new gateway from Eddie installed to prevent drain. I'm hoping I start the car tomorrow fine, just concerned that something is active whilst the car is stationery and not live.

I'm pretty sure it lasted around 3 hours!

I'll soon find out if it's worth worrying about tomorrow.

Post by: mvb12 on December 30, 2014, 08:46:20 am: the fan normally stays on for around 5 mins max after ignition off. 3 hours isn't the norm.
