TTG 700 & TT Rider

[Pils]

I am looking to purchase either the TTG 700 or the TT Rider. I have a bike and a car and would like to interchange the unit between the two. The Rider seemed the obvious choice but there appears to be some negatives in this choice. Can anyone shed any light on them:
The rider only has Europes main roads - the 700 has detailed Europe maps?
The rider has no speaker so you'd have to use the headset in the car?
Will there be a car kit for the rider to give talked directions? Tom Tom can't answer this...
Is there a headphone jack on the TTG 700 so I could wear this under my helmet? (I could use this for both bike and car then.)
Cheers, Mark

TomTom have not said much about the Rider fitting into a car but i cant see tomtom not doing this as the demand will be high. I have a CBR600 and would recommend that you look at the rider once it comes out as the 700 is not waterproof at all.
