I have a 2010 bmw 328i sedan. I have the base system for stereo. 2 speakers in front doors and 2 in rear deck lid. I dont have a factory amp. I installed a sony xav-ax5000 with the LC-BMRC-01 metra chime retention kit and ASWC-1 steering wheel control. The kit said I have to run a wire from battery to the sony head unit. I did that. Everything works as intended except I get the sos error which is understandable but my issue is when I let the car sit or it goes in to sleep mode it's slow to wake up. I hit unlock on key fob and it takes up to a minute or more sometimes before my lights come on, no dash or headlights either. I have done everything I can think of. Have you ever encountered this? Thanks for your time

Your battery is depleted from working on your car.
Try putting a full charge on it with a trickle charger or
battery tender .
A sure sign of a battery going bad is a weak start in the
morning.
Average life on battery's on these is 6 years.
measure the battery voltage in the morning before the
first start.
Battery is always the first thing to check before going
deeper.

Thank you ctuna for your reply. Do you think the wire from the battery to the new headunit is causing this? I dont have these problems if I hook the original radio back into the car. Thank you for your time. Just got this car in December and learning alot about it.

[ctuna]

You should be able to hook up the cable that
maintains settings for memory that shouldn't require
any significant current draw.

If the car is not going to sleep it will kill the battery
as the awake current is about .5 amps in these.

If you work on the car with the doors open and the battery
attached the car is awake . If the battery is already old and
marginal if can hasten its demise,

A lot of people have put in aftermarket decks without issues.

I had the car on the charger for several hours today. It's still taking a minute or so of it sits for a while to wake up

[ctuna]

You might try the new head unit by itself.

[blkbtty]

I'm wondering if it's the harness or i dont have the can + and - hooked up right?

[blkbtty]

Ok I figured it out. I had the LC-BMRC-01 harness with steering control and chime retention. With harness hooked up car was slow to wake up on unlock. Factory radio everything is normal. No radio hooked up and everything is normal. Something with that harness is messed up. I used the metra 70-9003 harness and everything works great. No chimes or steering control. I want to hook factory radio up to retain chimes but will this make my steering control work as well? Thank you

[ctuna]

There are a some harnesses out there that claim to do what you
want . Connects 2 comes to Mind and I thought Metra has
something to.

Or is the AX the one that is causing the problems

I have a factory radio so I am no expert on this the links I collected
and put up are as much as I know.

[blkbtty]

Any info is better than none. I appreciate you at least trying and your time. Yeah the metra one with the aswc-1 steering wheel control was the one that was causing it to not wake up from sleep like normal. Thought I'd put my feelers out there and see what I could find.

[Stubbie Blue]

In my 2012 135i E82 I used the PAC RadioPro RP4.2-BM21 smart harness for chimes and SWC, and it does not give an SOS error.

If you get an intermittent beep or your PDC doesn't work, you have to downgrade the firmware to 1.00.03 from the PAC website. Then everything should work fine.

[blkbtty]

Oh sweet thanks stubbie. I may just get that one then instead of hooking my factory radio up and hiding it somewhere.

[Akinari]

I'm having a similar issue. Put in a JVC head unit into my E93 328i the other day, everything works perfectly, steering wheel controls, chime, no functional issues at all.

The next morning, it took a few presses on my fob to unlock the car. I start the car (normal crank speed) and get FM radio static blast through the speakers at a ridiculous volume. I see the head unit time and date had reset, although the custom lighting and audio settings including BT were all saved.

I did keep the interior lights on for extended periods of time during the head unit install which took a few hours, but I never got an increase battery drain notice pop up on my dash.

Is this simply the battery being depleted or wearing out from that several hour-long install, or a more serious parasitic drain issue from the head unit?

Also, don't know if it's worth mentioning but I still have full factory chime functionality even though I removed my factory head unit that is NOT coming from the chime retention harness, is this normal? It's an 07 early production pre-LCI, dunno if they had separate chime modules.

[ctuna]

The 06's had a seperate chime speaker it seems to be dependent
on the stereo system. Idrive may not have them.
The fact the car is awake while you are working on it has more
to do with depleting the battery than interior lighting.
If the battery was old you might have hastened its demise.
The low battery warning is kind of hit and miss . You notice
things like long starts in the morning or the stereo won't stay on
in accessory mode before you ever get
the low battery warning.

Slow charge it.
Also you may not have hooked up to a constant on source
and if the battery voltage drops enough on start it resets everything.

[blkbtty]

Do you have the wire going to the head unit from the battery? Or tapped into a constant source?

Looks like I can't read instructions and didn't connect a wire to a constant power source (battery or fuse box). Will be doing that and should fix the head unit resetting.

Still doesn't explain the car not responding to key fob presses, I guess that may have more to do with the battery being low.

[blkbtty]

What harness you have?

Same Metra harness as you, with the integrated steering wheel control harness.

Going to try simply unplugging the chime module from the harness to see if it makes a difference, since I don't need the module anyway as my car although an '07, has a separate chime system.

[blkbtty]

If you hook stock radio up everything works correctly right? Hook it up and wait over 30 mins to see if it wakes up. Then try with no radio hooked up same thing 30 mins at least wait. That's what I did. I ended up using the metra 70-9003 for now then I will be trying the PAC harness.

blkbtty, I was curious if you ever got this figured out (steering controls and all)? A stereo shop installed the Sony XAV-AX5000 (same stereo) in my 2010 328i (same car) about a week ago. Everything worked great at first, but the next day when I went out to unlock the door, I noticed that the car didn't unlock. I started to freak out and after about a minute of hitting lock and unlock it opened (exact issue you described). It does this every morning and sometimes during the day. I'm taking it back to the shop next Tuesday for them to take a look but they sounded like they've never seen this issue, my BMW guy is telling me to have them re-install the old radio, and it would be great to be able to suggest to them about a combination of harness/steering wheel controls that worked properly with this car. I noticed that you found a harness that worked, did you ever get the steering wheel controls working too?
