IVA-W203/P1 starts screen shows than gray and wont do anything

what causes the screen to go red on my D310

Alpine only pays for certain mapping.
This unit will not have the same mapping that say a Garmin would have.

Not a solution, just commiseration - I've had the exact same problem with mine (apparently alpine is aware of the issue) and I've had about *15* different NVE-P1's in my dash to date so far AND i've had them replace the entire head unit as well. Still no dice. :-(

I don't know if this is related, but my Sirius cuts in and out like crazy too - sounds like a loose connection somewhere.

Suffice to say I will *never* be buying Alpine again!

I dont believe there are any updates for the P1 at this time.

Alpine does not have any updates to this 4-5 year old map at this time per Alpine tech support. It is the same out of date mapping as the BT200 - when available, it may be supplied for free... or at a charge from there website - support. Also, having problems with your iPhone 3G syncing your address book. Alpine is having me send in my NVE-P1 and they are replacing the hardware inside so that it will now sync. Also, iPod Touch, and iPhones need at least version 3.0 in order to display video to the W505 unit.

pls return the product, it might cause short circuit

The nav feature is purchased separatly with the deck, the previous owner did not purchase it because at the time alpine was charging an extra $1000 on top of the price of the deck to add nav. This is due to the fact that alpine decided to use there own reasearch and development team to design a nav system where as kenwood baught the rights to use garmin's technology and put there name on it which they only charge $400 on top of the price of head unit to add nav.

you have to bypass the parking brake in order to set the clock

If the head unit has a reset button try to reset it. if that doesn't work it will need to be sent to the manufacture to be repaired or replaced. But if someone broke it warranty doesn't cover that. Niether do most insurance companies without special coverage. Sorry.
