Help. I cant get the old Bose out to install RNS-E

I have got the keys that came with the RNS-E (four of them) and they click in place on the radio but upon pulling the keys release before the radio does??? Is there a trick or something I am missing?

2003 Audi A4 US B6 3.0Q with Bose upgraded stereo

Should I bite the bullet and just go to a stereo shop to get help?

Get a friend to help you, push the keys outside towards the doors while pulling, if this doesn't help remove glovebox or trim under steering wheel and push from behind. It will come out eventually.
Thanks I will give that a shot.
Yes, this is one of the little things not mentioned much. I bloodied my hands trying to get my original radio out using the keys. The rings on those little keys are sharp! The way I finally budged it is by sticking a couple of screwdrivers through the rings on two of the keys at a time (diagonally) and pulling really hard.
As I type with band-aids on my fingers... were you more succesful with a slow constant pull or a jerk it loose type action?
slow, constant, left then right then left and so on worked best for me
With mine, the top right key wouldn't lock, so pulling on it, just resulted in it coming out. I got mine out by pulling the top left and bottom right like AudiA4B6US said, "slow, constant [but really hard], left then right..." Also, as I said, using bare fingers on the rings is painful and futile. Either put on some leather gloves, or stick something through the rings that you can pull on less painfully.
One more idea - while a bit more time consuming, its pretty easy to remove the glove box (9 screws holding it in) and then just reach to the back of the radio and push it out (with the radio removal tools inserted, of course).

I had the same problem with one of the tools pulling right i took the extra 5 minutes and made this a simple, blood-free job! :)
Seems like many have troubles with the top right key. I found that if I put it in all the way to the "click" it would just pop out when I pulled really hard. I ended up pushing it in to just BEFORE the click and that seemed to disengage. I had already got the left side to come out a very slight amount without too much trouble. Getting the radio out was the hardest part in the entire RNS-E upgrade.
I am so glad that this is common, I was beginnning to doubt my abilities on working on an Audi Plug and Play installation... :)

I will try both the push before the click and the screwdriver through the keys method starting on left and moving to right and left the right, etc; and if I get any resistance will move to the push from behind option.

Thanks again for all the great advice.
you might want to remove the knee bolster or/and the glove box... both are really easy to remove and once removed you'll be able to push the unit from the back (keys still need to be inserted)... that's how i remove head units nowadays...
Removing the glove box and knee bolster does help a little, but if he is having the upper right key not disengaging like I did, no amount of force from the back was going to budge the radio. Not sure the internal anatomy of the A4, but in my RS6, I could barely access behind the radio so pushing from behing was not really an option - even with the glovebox and knee bolster out. I had read somewhere on a previous post about pushing the key only part in and that did the trick.
Sticking Bose unit

i had the same problem, and was afraid that if I applied too much pressure I would break something...I ended up going down to my friendly Audi dealer and having a technician do it for me...
Well it was a combination of removing both panels and pushing from behind and gently adjusting the keys until each one released. Very tricky...but now it is out :lol:
Great! As others have already said, you have now completed the most difficult part of the RNS-E installation.
