What do you think of these navigation systems?
 

My X5 does has the stock audio system (no OEM Navigation system) and I was looking to hook up my IPhone/aux (DICE, Etc.). Then I thought if I have to pay $150-$200, why not change the unit to an aftermarket indash system for a bit more.

What do you guys think of the units below?

Option A:
7" Car GPS Navigation DVD Player Radio Stereo HD iPod BMW 5 Series E39 E53 X5 | eBay

Option B:
7" Car GPS Navigation DVD Player Radio Stereo BT iPod BMW 5 Series E39 E53 x5 F | eBay

Option C:
Car DVD GPS Navigation Player for BMW 5 E39 BMW x5 E53 M5 BMW 520i 523i 525i | eBay

Option D:
7 Car DVD GPS Navigation Radio Player for BMW 5 Series E39 M5 x5 E53 iPod TV Map | eBay

Thanks

I dont think anyone got them that i remember but, keep in mind these are knock-off and from my experience with vw on non oem, the gps if its via sd card can be upgraded for somethng better. The sound, well depends on how picky you are...the biggest complaintsbi have heard has been on the radio reception. If you have xm radio hooked up to it then u'll be good to go.

Any personal experiences?

I think the general consensus with any of the Unbranded gps units is that you get what you pay for. Most of these are in the $300 range, while some of the double dins can run upwards of $1600+....personally I'd stay away in favor of one of the major brand units.

Fwiw, I had the pioneer f700bt, but upgraded 6 months later to the unit I currently have and it's Been absolutely great! Wouldn't hesitate to buy another!

I'd never use the GPS as I keep addresses saved in my phone, so just as long as I can pair my phone to the stereo via BT, then everything I'm playing via Pandora, GPS, etc will run through the stereo. My biggest desire for these aftermarket units is that it will still show the OBC functions and steering wheel controls work, has good video quality for playing DVD's, images/ screens of the actual menus like radio, ipod intergration, etc are nice high quality UI images vs the generic DOS looking versions I've seen of other decks.
