Time to upgrade the Navi disk on my '04 MDX, and will probably do the '06 RL as well. I know there are discounts to be had on OEM parts. Are there any available for Navi disks or am I stuck with the $185 from acuranavi.com? At least free shipping is available until tomorrow (01/31/10). The current ones (3.90, 4.81) don't come up on eBay often and end up selling for close to retail anyway.

Thanks.

Honestly, these RARELY go on sale.

My wife's an engineer at Honda, and Navi discs seem to be the only Honda/Acura related parts where she can get no discount at all.
