What I did not like and was VERY disappointing in was the Maestro RR interface. This was supposed to give me all the original functionality of my in car unit, plus all kinds of looks into the gauges and stuff like temp and oil pressure. I also thought it was supposed to simplify the hook up of the car stereo. Don't believe ANY of that!
First off, the instructions DID NOT match the unit I have. Connectors were different (changed) on the unit shipped from what the instructions show. No explanation on how to hook up the new wires.
Second, I still had to solder a LOT of wires. It may have simplified SOMEWHAT the soldering, but there is still a LOT more to do. I thought this was going to be plug and play. It is NOT.
There is also a lot of talk bout the My Vehicle options Myeastro is supposed to open up. While it is no big deal to me, I must be part cats cuz I do like sparkly things. But I got NOTHING here... just a USB interface. My Car HUD has all kinds of stuff- open doors, tire pressure, olil pressure, etc. Nada from Maestro.
But the thing that upsets me the most (and made me return this item!) is that the built in mic in my car was NOT recognized. Crutchfield Tech Support said,
"With the Pioneer stereo it is only possible to maintain the Bluetooth mic in Ford vehicles with the Sync system. In your VW you will need to use the mic that came with the Pioneer and use the Bluetooth built in to the radio."
So promises of using all the stuff you already have in your car is a load of hooey. This item is NOT cheap, and it is an add on to an already expensive item. It does NOT take away the soldering tasks, and it certainly does not come close to doing what it promises. If this was twenty bucks I could deal with this, but 150 bucks for some that barely works, underperformed and causes more work than it saves is NOT a product I would recommend.
I contacted iDatalink and got NO RESPONSE. Crutchfield responded quickly, but can't fix a bad product from iDataLink.
All in all this unit was a lot of broken promises and expectations...
