BSM is only available in the driver assistance package. It appears that there are two parts which both sit on a side mirror: sensor and display. It looks like the special mirror can be bought and replaced, then we ll have BSM. Has anyone tried this?

Part # is 22835039 and 22835040

All the online site shows a 15% restocking fee so if it doesn't work, well ...

Maybe one of our members who is a GM Tech with internal hookups can try and let us know if it works?

ok, so I found our that the BSM system needs 4 components: the 2 mirrors and the 2 radar sensor

Looking up on the GM parts site, there are 2 types of sensors residing in the rear bumper:

http://www.gmpartsdirect.co/auto-pa...6-flex-engine/electrical-cat/parking-aid-scat

_ radar sensor part # 22971863

_ object sensor part # 23133813

_ possibly also requires a special harness part # 23109287

Not sure which one of the two sensors I would need. Only way to find out is to open up the rear bumper.

Any one have a diy of how to remove the rear bumper?

I am very interested in this, so hopefully something comes of this. This was the only feature I wanted in that package. IMO it should be a standard feature.

I can adjust my mirrors to eliminate a blind spot big enough for a car to hide in. Motorcyclists are typically smart enough to avoid and loud enough to hear. It would be cool to be able to retrofit the blind spot feature anyway but I would definitely do the cross traffic mod if possible. I haven't figured a way to see thru the van that parked next to me when backing out.

the problem with all that is. the two modules are just that modules that need to communicate with the BCM and driver and passenger door module.
Without the Programing in the bcm this may not work.

However Gm is usually different and the features might just work without programing.

daddy, according to the info I posted above, the sensors for BSM also does the job os the cross traffic check. so it looks like one stone 2 birds here. only if I can find out for sure if ni reprogramming is needed...

on 19th of May, I ll have a spare car. I ll then attempt to open up the rear bumper and find out what sensors I need. worst case scenario is a loss of 15% restocking fee on a $300 sensor. oh well, I shall be the pioneer

just now found out that instead of buying the whole side mirror, I can just buy the mirror part which is much cheaper. Found couple of youtube on how to pry out the mirror part. Hopefully I wont mess up the assembly lol

interestingly, the right mirror is about $55 in comparison to the left which is about $97... strange...

^^^^^^ Please keep us posted.....only thing I do miss on my car, the BSM which is handy. The cost to get it with the the other bundled extras wasn't worth it IMO. If it could be retrofitted, I would love to do it also. Please take pictures as you go....be a nice step by step if it works :yup:

Looking forward to the results. I had BSM on my A4 and while I did not "need" it, it was a nice safety feature to have and honestly, should come standard on a luxury vehicle.

Very interested on how this turns out. I have the coupe and visibility isn't the greatest. I have done the mirror adjustment trick to mostly eliminate the blind spots but this would be a nice upgrade. This and the cross traffic were the only features I was interested in from the driver assist package, hence, I did not think the extra $3k was worth it.

Any update on your progress?

Any update on your progress?
