Pretty much. Although if you are able to, I would install the tuner yourself. I could see just the install being around 250.00 then whatever your dealer charges for the proxy. There are step by step pictures in the electronics Wiki section on how to get the tuner out which is what I used when I replaced my RE2 with the RB5 and its spot on. When I took it in for the proxy I left the glove box out just incase they needed to pull the tuner for anything.Thank you for the reply, that makes perfect sense. I've read this whole thread but I would like to summarize to make sure I'm understanding. I have a 15 Aero with Sirius radio. All I need to do is buy an RB5 unit for roughly 300-400 bucks have it installed and flashed for 200 ish? And voila I have nav correct? The only thing I won't have is directions in the TFT because there isn't a mainstream way of doing that yet correct?
As far as turn by turn on the instrument cluster it appears to be hit or miss. I didnt have NAV (obviously) or a TFT I don't get turn by turn on my TFT cluster. I seen another member his car had NAV but no TFT, he did a TFT upgrade he gets turn by turn on his TFT. Not sure what the requirements are if its a certain part # TFT cluster and certain part # RB5 tuner or what...but its not a huge deal to just glance over at the 8.4.
- Purchase RB5 Tuner
- Make sure to get Anti-Theft code for the tuner.
- If you can't get the tuner try and get the VIN of the car it came out of
- Take pictures of the label on top of the tuner with the part # and serial #.
* I've heard all they really need is the serial number but I was able to get the VIN and I wrote in sharpie on the tuner and took pictures of it with my phone.
- Install new RB5
- Go to dealer and get proxy alignment.
Just make sure to tell them you need the anti-theft code, the guy at the parts counter will take whatever info you have and try and retrieve it from the system. Then just make sure you get the anti-theft code and log it somewhere.
