Your phone on the other hand uses its own service which is two-way: you have to participate yourself and "upload" jams as you encounter them, which are then pushed to all the other phones. This may be a better system (especially with the large userbase of the iPhone) but it requires a data connection via GSM. The Evoque will only use TMC and I haven't seen interactive systems in cars yet.
The first OEM's start to deliver live traffic systems in there cars. BMW is one of them. This technique give the user better results because of the real-time data.
You are right. It needs a GSM or better a 3G communication. But is this a big deal today? I think not. You get so many advantages if you get real-time data.
parking deck, traffic jam, google etc..
If RR wants to sell premium cars, in my eyes such technology have to be available as option.
Should I still use my iphone for navigation????
