Is it the GPS chip not refreshing quickly enough or is it the actual screen not refreshing enough.

As you said, same GPS chip but larger screen..the GPS chip was originally designed with a smaller resolution in mind so ... /shrug

iguidance VGA works flawlessly on my girls diamond, but on my TP the lag is unbearable. I thought the diamond and TP has the same GPS chip? if that is true them someone needs to look at the diamonds GPS drivers and get some porting done.
