The system is very good. Bluetooth phone function works great and call quality is very clear. Doesn't take too long to install and the mic can be routed via the A pillar and across the bottom of the dash over the pedals.
I found that you may be able to get away from using the ariel booster as I seem to pick up stations quite clearly and the auto scanning function for RDS station is quite good.
You may also want to know that the aerial booster from Nexxia is incompatable as I'm still waiting for a response back from them regarding the correct part. You will also need the facia kit as the standard stereo is very wide and leaves two gaps either side when replaced with an after market.
Lastly the IPod interface is really good as you can select tracks using the beker unit.
Let me know if you need any further info.
