I love my RB1 unit. A few things I hope they change in upcoming software releases:
1. When you're zoomed in, it appears that there are a great number of streets that are not identified on the screen with their names. I understand if the name won't "fit", it won't be shown, but there are many times when it will fit but still isn't shown.
2. The lady's voice is very "bassy," which makes it hard to hear in certain situations. I'd like to be able to EQ her.
3. They've alloted WAY too much room for the radio/satellite identifier in the lower right corner. All you need is the channel number. I know if I'm on SAT or FM. The rest of the room should be given to the other side of the screen where the name of the street you're currently on is shown. Too many times is the name of the street cut off, or the town you're in is not shown at all.
Funny story about my RB1.... I was in the outer banks a few months ago on a ferry. I had my car on from time to time (2 hour trip), and my RB1 never updated its position even though were were moving. I assumed it was because the CAR wasn't moving under it's own power, so the RB1 didn't think we were actually moving. It wasn't until I drove off the boat that the screen refreshed.
