Default TCU's and ULF's

do our cars have both, or is it one or the other? I have an iPhone and have read that for optimal handsfree use, that an upgrade to a 13th generation ULF is needed.

Others can correct me if I'm wrong but I believe it's one or the other. If you have BMW Assist, you have the TCU (b/c it has built-in cell phone circuitry so that it can dial out to Assist). If only Bluetooth, then the ULF. If none, then by all means get the ULF. Martin at Bimmernav.com will probably be able to answer all your questions and probably has the info you need on his site.

TCU: Installed by the factory. For 2004 and earlier cars the TCU only had Assist and no bluetooth. To add Bluetooth to a 2004 and earlier car you pull the TCU (and loose Assist) and swap in a ULF, add a bluetooth antenna and pairing button. The ULF was only an dealer installed accessory, never installed by the factory. For 2005 and 2006 E46 cars if you ordered Assist, the factory installed a TCU that included bluetooth.

Notes:
TCUs are made by Motorola and ULFs are made by Visteon.

ULFs require a pairing button, TCUs do not.

There were some 2004 cars that came with documentation from the factory that they had bluetooth but the TCU actually did not have it.

The ULF can be retrofitted to cars that did not have Assist (see EAS or BimmerNav).

For some later model non-bluetooth cars (2004?) you can install at TCU rather than a ULF, but TCUs are relatively expensive (if buying from a dealer).

There are 13 versions of the ULF, apparently only the 13th version works with the iPhone. The 1st generation (sold by most US BMW dealers) was notoriously buggy and worked with very few phones. Later models worked with many phones (except of course, the iPhone). I don't know about compatibility of TCUs with the iPhone.

There are both GSM and CDMA TCUs. I believe on the CDMA TCUs work in the US. The GSM ones are for Europe, though there are people selling them in the US on ebay, be careful, I don't think you can even get the bluetooth part of the GSM TCUs to work in the US.

TCUs (except early 2005 ones) include voice controlled dialing. ULFs have voice controlled dialing and voice controlled navigation commands.

Default bluetooth in a 2004 M3 with Assist

I have a 2004 M3 with Assist, navigation, and pre-wiring for cell phone. If I want bluetooth capabilities, do you think my best option is to get the Bimmernav kit for $695? It sounds kind of expensive for what it is. Has anyone tried this kit? Will the system really be able to accept voice commands for dialing and so on? I would probably stay away from the eject kit just because it is fitted for individual phones. Phones change too often to deal with this.

That's what I did, but I went with Tom@EAS. I am very happy with the switch, all the voice commands work well, it works just fine with the iPhone - but be aware that the iPhone sends names with the number type, e.g. (mobile), or (home) so the caller ID display is a bit useless.

The install is very easy, it took me about half an hour to get it all done.

Default EAS bluetooth

Thanks Ian! Do you know the part number of what you bought from EAS? Do you know if there is any difference from Bimmernav?

The 13th Gen ULF has specific iPhone compatibility, but if someone is in the SoCal area with a n95 - we'll be happy to pair up the phone and find out for others on the forum.

There is just the module: http://www.europeanautosource.com/pr...5c2bbf71b383b1

Or a full upgrade kit with all the other bits and pieces (I bought the full kit): http://www.europeanautosource.com/pr...5c2bbf71b383b1
