I am in the final days before my 535i goes into production and I want to ensure I have all the necessary hardware for TJA (5AR) in the order. I've got Driver Assistance Package and Driver Assistance Plus with ACC Stop & Go.
Based on my read of the available literature, this should equip the car with the necessary hardware, right? It seems like Parking Assist shouldn't be required, but that's the one I am least sure about. I'll worry about the actual coding part when I get there. |

I didn't think TJA was available for the US market, and it's unlikely to be retro fit. TJA works with different software for the ACC than standard DA+ although both use a front camera/radar, mounted in the grill. It also has a steering wheel with pressure sensors to ensure that at least 2 fingers are in contact with the wheel at all times. This works in conjunction with the Lane Departure Warning system, as it steers the car between the white lines. Last edited by archivedaccount; 01-07-2014 at 03:14 PM.. |

Has anyone been delivered a car with TJA yet ?
Mine went into production the first day it was available and is still not delivered So in the meantime I was wondering if anyone had hands-on experience ? |

Looking forward to hearing all about it. It's got to be great with the morning commute. I use distronic on my MB, but of course that doesn't have the steering. Can't wait to try it.

Just got my F15, 30D delivered today in Switzerland, production date was 27.11.2013 and including TJA, so looks like first production dates with TJA included as I pushed on having it on.
Really nice , but indeed only works on highways. It detects the moment you get on the highway and will activate to use it, warning that it will only work up to 40km/h. Still need to test out fully in full traffic, so will post once in full use. RTT on top of it is great. You always see all major roads colored in green, yellow and red, knowing where the traffic is rolling ... but of once I'm looking forward to get more in jams for the moment BTW: not missing the active steering at all ... moves around like a charm ... |

Here we got about the first experience in some traffic jam with TJA on.
First I have RTT on, so you see immediately where the traffice is flowing and where not. Note it tells me the delays in minutes. For me this is new, so really nice and very accurate! Then to turn it on use the smaller button on the bottom right. if not on the high ways you will get the message that it will only work on the highways (or Autobahn). here in German, circled: So get on the Autobahn, here we go, it will activate warning it will work only for speed up to 40 km/h: Now hope for a jam, where you go below 40km/h, now fun starts: 1) Set your cruise control to whatever speed (can be 120km/h), if the TJA was activated it will automatically pop in, once your car slowls you down automatically to below 40 (or whatever the car is driving in front of you). once you are below 40km/h the steering pops in too, showing up with the little steering symbol between the lines ... so now just keep your hands on the steering wheels, otherwise you get the warning on the HUD and also in the control panel ... now enjoy the traffic jam and relax, it works like a charm. I did not get into a full stop jam yet, to see what happens when you stop ... Last edited by Dopas; 01-24-2014 at 06:05 PM.. |

Great post thanks! With the RTTI, does it use the updated traffic info to offer the best possible alternative route e.g. Route1 takes 20mins+10 min delay total 30 mins, route 2 takes 25 mins+6 mins delay, Route3 takes 28 mins no delays, so in this scenario it should select Route 3. Tomtom with hd traffic works like that and is excellent.
How does the TJA know if it's on a motorway? Maybe uses the satnav map data? |

I wanted tja on my configuration but it is not compatible with active steering, which automatically comes with m sport package in France. I ll still get ACC+ and everything else, so maybe later that feature could be activated with an update when they manage to get it work with active steering ?

I don't think the steering wheel itself is different, because it would be too complicated for Bmw to maintain 2 versions of each model (base, sport, M which I ll have) , I think it is just "disabled" but hardware is here. I ll check on Bmw etk though.
Edit: I checked on etk and yes you re right the steering wheel has different part number, + there is an additional "HOD" electronic device in it. Would be curious to know what would happen if we retrofit theses components and reactivate the functionality in the car ^^ Anyway I can deal without this functionality in traffic jam, because we need to keep both hands on the steering wheel which means I cannot play with my iPhone or go on this forum while stuck in traffic jam Last edited by w4termelon; 01-25-2014 at 06:41 AM.. |

RTTI uses the moving object information, meaning each BMW wit RTTI, but also some trucks and taxis. So it's very accurate, updated every three minute, using the speeds of the cars on the streets. For re-routing it will use all its available information as it also gets RTTI for non-highways, so also major streets specifically in cities. So it tries to route you optimally, using all available traffic info. TJA knows you're on a highway through your GPS position. Last edited by Dopas; 01-27-2014 at 02:54 AM.. |

This may sound like sour grapes, because I'm in the USA and may not see this kind of stuff for years here, but what good does it do to have the car help you with steering if you have to keep both hands on the wheel? Or can you get away with one hand (for periods of time)?

One hand works for me. Who claims two hands?
See also: http://www.bmw.com/com/en/newvehicle...stant.html#t=l BTW, at a full stop you need to do some action to get it going again. Push Gas, or Press resume .... |
