Parents have a Sony for their car. I'd advise against that UT-87 or something. Thing is slow as molasses even with current update.
Personally i'm probably going to get a Nuvi 760. Bluetooth and multi-point routing. $200 on Amazon and I have gift certs there to help me. While a Zumo might be nice it's over double the price. I'd rather put that money towards some other gear.
