I get oil temp.

Thanks! Can anyone with a 4.4 also confirm they get oil temp?

What?? Really? I was told the E53 oil temp data is not on IBUS. There's is an oil temp sender in the oil filter assembly alright, but it's connected directly to the DME and not sent to the IBUS from there and therefore it's not a reading accessible via OBDII, either. That was the explanation I read somewhere. In any case, could you please post a pic?

The ibus dev says the oil temp comes from the TÖNS which is on the bottom of the oil pan. I believe the signal routes through the LCM. Mine didn't work with my original LCMIII or the replacement LCMIV I put in a few years ago.

I've ordered a new Hella TÖNS to swap in.

You mean the oil level sensor at the bottom of the pan? It has a temp sensor ability too?. Kindly update on your findings after the swap.

Installed my Avant 4 yesterday and have a few Q's for the experts in the room please.

1) I'm not getting any radio signal, and I see there's an antenna plug on the back of the head unit - just no antenna connector in the dash. Should the radio signal be coming in thru one of the zillion other wires running to the rear of the truck, or did I botch something?

2) The unit came with a GPS antenna and a long mystery cable that could be for GPS also. Did AVIN send two different GPS connection options? I don't plan to use the built-in GPS.

I'm about to start buttoning up the exploded interior, but want to be sure I've run all the wires I need (back-up camera and quad lock cables). Anything else? Again, not planning to run GPS. THANKS for the help!

There is a separate radio antenna cable that needs to be plugged in.

I assume (you don't specify) that you're replacing a nav system and ran cable to from the trunk to the dash. There should be a cable that plugs into the antenna wire that gets removed from the radio module in the trunk.

If you had the non-nav radio in the dash, you should have a antenna cable in the dash.

Yes the OE unit had nav, so I ran the bundle of new cables to the luggage area. Sound like i need to run an additional cable especially for the antenna. Right?

Yes. Or, do like I did (though Avin doesn't provide a cable for it) and tap into one of the antennas in the center console. It's located on the left hand side about half way down the console. I believe it was originally for the factory phone connection in the armrest area but is serviceable as a radial for the AM/FM. At least it was for my installation.

I found that connector in the console (circled in first picture below), but it was the same style as the one coming from the new head unit. Both are female/female or male/male type.

After a ton of searching for info on the antenna situation and mistakenly tearing apart the left side of the luggage area, I finally discovered that the AVIN-supplied antenna cable plugs into the antenna supply line going into the OEM radio unit. (second pic) This is the best option, since it makes use of all the crazy tech that BMW installed for simple radio signal reception. I'm lookin' at you, diversity antenna, signal amplifier, trap circuit and AM/FM1/FM2/FM3 separate antennas!!
