I also want to know what is INITLOCATION.
I made a search, and I found that people use different values for INITLOCATION (like 8) even it's limited to values 0-1-2
I couldn't get it.
and the description is not very helpful for me
INITLOCATION (0, 1 or 2): use cold, warm or hot boot for PSP-290 GPS receiver
I also have PSP-290.
