Firmware Update 4.0

I downloaded the new update to my Nuvi 350. They still haven't fixed the currency convertor. When I use POI Loader it fails after it asks about the last file in my POI folder on my PC harddrive. I have tried it several times. I deleted the last file in my PC folder - still no luck. I tried removing all custom POI - it still fails. I deleted the POI folder off the Garmin 350 drive - it still fails. Is anybody else having trouble loading custom POI's after the update! Help!

I updated my 750 to 4.0 about a month ago, then went on a three week 2000 mile trip, so it got a good workout. Like many others, I experienced the voice delay, and it does seem to take longer to load maps than it did with 3.2. I'm going to update to 4.1 today to see if there's any improvement. I'll report back when I've had a chance to test it out.

No improvement on the lag thing that I've noticed.

I used my 750 in track up, 2D, installed a older 1.80 voice and still have the lag issue. Is has not caused me to miss a turn yet but is annoying that the lag was not fixed. At least it's not locking up like it did with 3.10
